-  Flagship Heterogeneous Architecture (No Carry Chains) for VTR 7.0.
-
-  - 40 nm technology
-  - General purpose logic block: 
-    K = 6, N = 10, fracturable 6 LUTs (can operate as one 6-LUT or two 5-LUTs with all 5 inputs shared) 
-    with optionally registered outputs
-  - Memory size 32 Kbits, memory aspect ratios vary from a data width of 1 to data width of 64.  
-    Height = 6, found on every (8n+2)th column
-  - Multiplier modes: one 36x36, two 18x18, each 18x18 can also operate as two 9x9.  
-    Height = 4, found on every (8n+6)th column
-  - Routing architecture: L = 4, fc_in = 0.15, Fc_out = 0.1
-
-  Details on Modelling:
-
-  The electrical design of the architecture described here is NOT from an 
-  optimized, SPICED architecture.  Instead, we attempt to create a reasonable 
-  architecture file by using an existing commercial FPGA to approximate the area, 
-  delay, and power of the underlying components. This is combined with a reasonable 40 nm 
-  model of wiring and circuit design for low-level routing components, where available.
-  The resulting architecture has delays that roughly match a commercial 40 nm FPGA, but also 
-  has wiring electrical parameters that allow the wire lengths and switch patterns to be 
-  modified and you will still get reasonable delay results for the new architecture.
-  The following describes, in detail, how we obtained the various electrical values for this 
-  architecture.
-
-  Rmin for nmos and pmos, routing buffer sizes, and I/O pad delays are from the ifar 
-  architecture created by Ian Kuon: K06 N10 45nm fc 0.15 area-delay optimized architecture. 
-  (n10k06l04.fc15.area1delay1.cmos45nm.bptm.cmos45nm.xml)      
-  This routing architecture was optimized for 45 nm, and we have scaled it linearly to 40 nm to 
-  match the overall target (a 40 nm FPGA).
-
-  We obtain delay numbers by measuring delays of routing, soft logic blocks, 
-  memories, and multipliers from test circuits on a Stratix IV GX device 
-  (EP4SGX230DF29C2X, i.e. fastest speed grade). For routing, we took the average delay of H4 and V4 
-  wires.  Rmetal and Cmetal values for the routing wires were obtained from work done by Charles 
-  Chiasson. We use a 96 nm half-pitch (corresponding to mid-level metal stack 40 nm routing) and 
-  take the R and C data from the ITRS roadmap.  
-
- For the general purpose logic block, we assume that the area and delays of the Stratix IV 
-  crossbar is close enough to the crossbar modelled here.  We use 40 inputs and 20 feedback lines in 
-  the cluster and a full crossbar, leading to 60:1 multiplexers in front of each BLE input.
-  Stratix IV uses 52 inputs and 20 feedback lines, but only a half-populated crossbar, leading to 
-  36:1 multiplexers.  We require 60 such multiplexers, while Stratix IV requires 88 for its more
-  complex fracturable BLEs + the extra control signals. We justify this rough approximation as follows: 
-  The Stratix IV crossbar has more inputs (72 vs. 60) and 
-  outputs (88 vs. 60) than our full crossbar which should increase its area and delay, but the 
-  Stratix IV crossbar is also 50% sparse (each mux is 36:1 instead of 60:1) which should reduce its 
-  area and delay.  The total number of crossbar switch points is roughly similar between the two 
-  architectures (3160 for SIV and 3600 for the academic architecture below), so we use the area 
-  & delay of the Stratix IV crossbar as a rough approximation of our crossbar.
-
-  For LUTs, we include LUT 
-  delays measured from Stratix IV which is dependant on the input used (ie. some 
-  LUT inputs are faster than others).  The CAD tools at the time of VTR 7 does 
-  not consider differences in LUT input delays.
-
-  Logic block area numbers obtained by scaling overall tile area of a 65nm 
-  Stratix III device, (as given in Wong, Betz and Rose, FPGA 2011) to 40 nm, then subtracting out 
-  routing area at a channel width of 300. We use a channel width of 300 because it can route 
-  all the VTR 6.0 benchmark circuits with an approximately 20% safety margin, and is also close to the
-  total channel width of Stratix IV. Hence this channel width is close to the commercial practice of
-  choosing a width that provides high routability. The architecture can be routed at different channel
-  widths, but we estimate the tile size and hence the physical length of routing wires assuming
-  a channel width of 300.
-
-  Sanity checks employed:
-    1.  We confirmed the routing buffer delay is ~1/3rd of total routing delay at L = 4. This matches 
-        common electrical design.

-    <!-- This multiplier can operate as a 36x36 multiplier that can fracture to two 18x18 multipliers each of which can further fracture to two 9x9 multipliers 
-	   For delay modelling, the 36x36 DSP multiplier in Stratix IV has a delay of 1.523 ns + 1.93 ns
-	    = 3.45 ns. The 18x18 mode doesn't need to sum four 18x18 multipliers, so it is a bit
-	   faster: 1.523 ns for the multiplier, and 1.09 ns for the multiplier output block.
-	    For the input and output interconnect delays, unlike Stratix IV, we don't
-	   have any routing/logic flexibility (crossbars) at the inputs.  There is some output muxing
-	   in Stratix IV and this architecture to select which multiplier outputs should go out (e.g.
-	   9x9 outputs, 18x18 or 36x36) so those are very close between the two architectures. 
-	   We take the conservative (slightly pessimistic)
-           approach modelling the input as the same as the Stratix IV input delay and the output delay the same as the Stratix IV DSP out delay.
-	   
-     We estimate block area by using the published Stratix III data (which is architecturally identical to Stratix IV)
-	     (H. Wong, V. Betz and J. Rose, "Comparing FPGA vs. Custom CMOS and the Impact on Processor Microarchitecture", FPGA 2011) of 0.2623 
-		 mm^2 and scaling from 65 to 40 nm to obtain 0.0993 mm^2. That area is for a DSP block with approximately 2x the functionality of 
-		 the block we use (can implement two 36x36 multiplies instead of our 1, eight 18x18 multiplies instead of our 4, etc.). Hence we 
-		 divide the area by 2 to obtain 0.0497 mm^2. One minimum-width transistor units = 60 L^2 (where L = 40 nm), so is 518,000 MWTUS. 
-		 That area includes routing and the connection block input muxes.  Our DSP block is four 
-		 rows high, and hence includes four horizontal routing channel segments and four vertical ones, which is 4x the routing of a logic 
-		 block (single tile). It also includes 3.6x the outputs of a logic block, and 1.8x the inputs. Hence a slight overestimate of the routing
-		 area associated with our DSP block is four times that of a logic tile, where the routing area of a logic tile was calculated above (at W = 300)
-		 as 30481 MWTAs. Hence the (core, non-routing) area our DSP block is approximately 518,000 - 4 * 30,481 = 396,000 MWTUs.

-           Area and delay based off Stratix IV 9K and 144K memories (delay from linear interpolation, Tsu(483 ps, 636 ps) Tco(1084ps, 1969ps)).  
-           Input delay = 204ps (from Stratix IV LAB line) - 72ps (this architecture does not lump connection box delay in internal delay)
-           Output delay = M4K buffer 50ps
-
-           Area is obtained by appropriately scaling and adjusting the published Stratix III (which is architecturally identical to Stratix IV)
-           data from H. Wong, V. Betz and J. Rose, "Comparing FPGA vs. Custom CMOS and the Impact on Processor Microarchitecture", FPGA 2011.
-           Linearly interpolating (by bit count) between the M9k and M144k areas to obtain an M32k (our RAM size) point yields a 65 nm area of
-           of 0.153 mm^2. Interpolating based on port count between the RAMs would instead yield an area of 0.209 mm^2 for our 32 kB RAM; since 
-           bit count accounts for more area than ports for a RAM this size we choose the bit count interpolation; however, since the port interpolation
-           is not radically different this also gives us confidence that interpolating based on bits is OK, but slightly underpredicts area.
-           Scaling to 40 nm^2 yields .0579 mm^2, and converting to MWTUs at 60 L^2 / MWTU yields 604,000 MWTUs. This includes routing. A Stratix IV
-           M9K RAM is one row high and hence has one routing tile (one horizonal and one vertical routing segment area). An M144k RAM has 8 such tiles.
-           Linearly interpolating on
-           bits to 32 kb yields 2.2 routing tiles incorporated in the area number above. The inter-block routing represents 30% of the area of a logic 
-           tile according to D. Lewis et al, "Architectural Enhancements in Stratix V," FPGA 2013. Hence we should subtract 0.3 * 2.2 * 84,375 MWTUs to
-           obtain a RAM core area (not including inter-block routing) of 548,000 MWTU areas for our 32 kb RAM in a 40 nm process.

-  Flagship Heterogeneous Architecture (No Carry Chains) for VTR 7.0.
-
-  - 40 nm technology
-  - General purpose logic block: 
-    K = 6, N = 10, fracturable 6 LUTs (can operate as one 6-LUT or two 5-LUTs with all 5 inputs shared) 
-    with optionally registered outputs
-  - Memory size 32 Kbits, memory aspect ratios vary from a data width of 1 to data width of 64.  
-    Height = 6, found on every (8n+2)th column
-  - Multiplier modes: one 36x36, two 18x18, each 18x18 can also operate as two 9x9.  
-    Height = 4, found on every (8n+6)th column
-  - Routing architecture: L = 4, fc_in = 0.15, Fc_out = 0.1
-
-  Details on Modelling:
-
-  The electrical design of the architecture described here is NOT from an 
-  optimized, SPICED architecture.  Instead, we attempt to create a reasonable 
-  architecture file by using an existing commercial FPGA to approximate the area, 
-  delay, and power of the underlying components. This is combined with a reasonable 40 nm 
-  model of wiring and circuit design for low-level routing components, where available.
-  The resulting architecture has delays that roughly match a commercial 40 nm FPGA, but also 
-  has wiring electrical parameters that allow the wire lengths and switch patterns to be 
-  modified and you will still get reasonable delay results for the new architecture.
-  The following describes, in detail, how we obtained the various electrical values for this 
-  architecture.
-
-  Rmin for nmos and pmos, routing buffer sizes, and I/O pad delays are from the ifar 
-  architecture created by Ian Kuon: K06 N10 45nm fc 0.15 area-delay optimized architecture. 
-  (n10k06l04.fc15.area1delay1.cmos45nm.bptm.cmos45nm.xml)      
-  This routing architecture was optimized for 45 nm, and we have scaled it linearly to 40 nm to 
-  match the overall target (a 40 nm FPGA).
-
-  We obtain delay numbers by measuring delays of routing, soft logic blocks, 
-  memories, and multipliers from test circuits on a Stratix IV GX device 
-  (EP4SGX230DF29C2X, i.e. fastest speed grade). For routing, we took the average delay of H4 and V4 
-  wires.  Rmetal and Cmetal values for the routing wires were obtained from work done by Charles 
-  Chiasson. We use a 96 nm half-pitch (corresponding to mid-level metal stack 40 nm routing) and 
-  take the R and C data from the ITRS roadmap.  
-
- For the general purpose logic block, we assume that the area and delays of the Stratix IV 
-  crossbar is close enough to the crossbar modelled here.  We use 40 inputs and 20 feedback lines in 
-  the cluster and a full crossbar, leading to 60:1 multiplexers in front of each BLE input.
-  Stratix IV uses 52 inputs and 20 feedback lines, but only a half-populated crossbar, leading to 
-  36:1 multiplexers.  We require 60 such multiplexers, while Stratix IV requires 88 for its more
-  complex fracturable BLEs + the extra control signals. We justify this rough approximation as follows: 
-  The Stratix IV crossbar has more inputs (72 vs. 60) and 
-  outputs (88 vs. 60) than our full crossbar which should increase its area and delay, but the 
-  Stratix IV crossbar is also 50% sparse (each mux is 36:1 instead of 60:1) which should reduce its 
-  area and delay.  The total number of crossbar switch points is roughly similar between the two 
-  architectures (3160 for SIV and 3600 for the academic architecture below), so we use the area 
-  & delay of the Stratix IV crossbar as a rough approximation of our crossbar.
-
-  For LUTs, we include LUT 
-  delays measured from Stratix IV which is dependant on the input used (ie. some 
-  LUT inputs are faster than others).  The CAD tools at the time of VTR 7 does 
-  not consider differences in LUT input delays.
-
-  Logic block area numbers obtained by scaling overall tile area of a 65nm 
-  Stratix III device, (as given in Wong, Betz and Rose, FPGA 2011) to 40 nm, then subtracting out 
-  routing area at a channel width of 300. We use a channel width of 300 because it can route 
-  all the VTR 6.0 benchmark circuits with an approximately 20% safety margin, and is also close to the
-  total channel width of Stratix IV. Hence this channel width is close to the commercial practice of
-  choosing a width that provides high routability. The architecture can be routed at different channel
-  widths, but we estimate the tile size and hence the physical length of routing wires assuming
-  a channel width of 300.
-
-  Sanity checks employed:
-    1.  We confirmed the routing buffer delay is ~1/3rd of total routing delay at L = 4. This matches 
-        common electrical design.

-    <!-- This multiplier can operate as a 36x36 multiplier that can fracture to two 18x18 multipliers each of which can further fracture to two 9x9 multipliers 
-	   For delay modelling, the 36x36 DSP multiplier in Stratix IV has a delay of 1.523 ns + 1.93 ns
-	    = 3.45 ns. The 18x18 mode doesn't need to sum four 18x18 multipliers, so it is a bit
-	   faster: 1.523 ns for the multiplier, and 1.09 ns for the multiplier output block.
-	    For the input and output interconnect delays, unlike Stratix IV, we don't
-	   have any routing/logic flexibility (crossbars) at the inputs.  There is some output muxing
-	   in Stratix IV and this architecture to select which multiplier outputs should go out (e.g.
-	   9x9 outputs, 18x18 or 36x36) so those are very close between the two architectures. 
-	   We take the conservative (slightly pessimistic)
-           approach modelling the input as the same as the Stratix IV input delay and the output delay the same as the Stratix IV DSP out delay.
-	   
-     We estimate block area by using the published Stratix III data (which is architecturally identical to Stratix IV)
-	     (H. Wong, V. Betz and J. Rose, "Comparing FPGA vs. Custom CMOS and the Impact on Processor Microarchitecture", FPGA 2011) of 0.2623 
-		 mm^2 and scaling from 65 to 40 nm to obtain 0.0993 mm^2. That area is for a DSP block with approximately 2x the functionality of 
-		 the block we use (can implement two 36x36 multiplies instead of our 1, eight 18x18 multiplies instead of our 4, etc.). Hence we 
-		 divide the area by 2 to obtain 0.0497 mm^2. One minimum-width transistor units = 60 L^2 (where L = 40 nm), so is 518,000 MWTUS. 
-		 That area includes routing and the connection block input muxes.  Our DSP block is four 
-		 rows high, and hence includes four horizontal routing channel segments and four vertical ones, which is 4x the routing of a logic 
-		 block (single tile). It also includes 3.6x the outputs of a logic block, and 1.8x the inputs. Hence a slight overestimate of the routing
-		 area associated with our DSP block is four times that of a logic tile, where the routing area of a logic tile was calculated above (at W = 300)
-		 as 30481 MWTAs. Hence the (core, non-routing) area our DSP block is approximately 518,000 - 4 * 30,481 = 396,000 MWTUs.

-           bit count accounts for more area than ports for a RAM this size we choose the bit count interpolation; however, since the port interpolation
-           is not radically different this also gives us confidence that interpolating based on bits is OK, but slightly underpredicts area.
-           Scaling to 40 nm^2 yields .0579 mm^2, and converting to MWTUs at 60 L^2 / MWTU yields 604,000 MWTUs. This includes routing. A Stratix IV
-           M9K RAM is one row high and hence has one routing tile (one horizonal and one vertical routing segment area). An M144k RAM has 8 such tiles.
-           Linearly interpolating on
-           bits to 32 kb yields 2.2 routing tiles incorporated in the area number above. The inter-block routing represents 30% of the area of a logic 
-           tile according to D. Lewis et al, "Architectural Enhancements in Stratix V," FPGA 2013. Hence we should subtract 0.3 * 2.2 * 84,375 MWTUs to
-           obtain a RAM core area (not including inter-block routing) of 548,000 MWTU areas for our 32 kb RAM in a 40 nm process.
