<!-- VB & JL: Using Ian Kuon's transistor sizing and drive strength data for routing, at 40 nm. Ian used BPTM
|
||||
models. We are modifying the delay values however, to include metal C and R, which allows more architecture
|
||||
experimentation. We are also modifying the relative resistance of PMOS to be 1.8x that of NMOS
|
||||
(vs. Ian's 3x) as 1.8x lines up with Jeff G's data from a 45 nm process (and is more typical of
|
||||
45 nm in general). I'm upping the Rmin_nmos from Ian's just over 6k to nearly 9k, and dropping
|
||||
RminW_pmos from 18k to 16k to hit this 1.8x ratio, while keeping the delays of buffers approximately
|
||||
lined up with Stratix IV.
|
||||
We are using Jeff G.'s capacitance data for 45 nm (in tech/ptm_45nm).
|
||||
Jeff's tables list C in for transistors with widths in multiples of the minimum feature size (45 nm).
|
||||
The minimum contactable transistor is 2.5 * 45 nm, so I need to multiply drive strength sizes in this file
|
||||
by 2.5x when looking up in Jeff's tables.
|
||||
The delay values are lined up with Stratix IV, which has an architecture similar to this
|
||||
proposed FPGA, and which is also 40 nm
|
||||
C_ipin_cblock: input capacitance of a track buffer, which VPR assumes is a single-stage

<!-- VB: the mux_trans_size and buf_size data below is in minimum width transistor *areas*, assuming the purple
|
||||
book area formula. This means the mux transistors are about 5x minimum drive strength.
|
||||
We assume the first stage of the buffer is 3x min drive strength to be reasonable given the large
|
||||
mux transistors, and this gives a reasonable stage ratio of a bit over 5x to the second stage. We assume
|
||||
the n and p transistors in the first stage are equal-sized to lower the buffer trip point, since it's fed
|
||||
by a pass transistor mux. We can then reverse engineer the buffer second stage to hit the specified
|
||||
buf_size (really buffer area) - 16.2x minimum drive nmos and 1.8*16.2 = 29.2x minimum drive.
|
||||
I then took the data from Jeff G.'s PTM modeling of 45 nm to get the Cin (gate of first stage) and Cout
|
||||
(diff of second stage) listed below. Jeff's models are in tech/ptm_45nm, and are in min feature multiples.
|
||||
The minimum contactable transistor is 2.5 * 45 nm, so I need to multiply the drive strength sizes above by
|
||||
2.5x when looking up in Jeff's tables.
|
||||
Finally, we choose a switch delay (58 ps) that leads to length 4 wires having a delay equal to that of SIV of 126 ps.
|
||||
This also leads to the switch being 46% of the total wire delay, which is reasonable. -->

<!--- VB & JL: using ITRS metal stack data, 96 nm half pitch wires, which are intermediate metal width/space.

With the 96 nm half pitch, such wires would take 60 um of height, vs. a 90 nm high (approximated as square) Stratix IV tile so this seems

reasonable. Using a tile length of 90 nm, corresponding to the length of a Stratix IV tile if it were square. -->

<!--- Area calculation: Total Stratix IV tile area is about 8100 um^2, and a minimum width transistor
|

area is 60 L^2 yields a tile area of 84375 MWTAs.
|

Routing at W=300 is 30481 MWTAs, leaving us with a total of 53000 MWTAs for logic block area
|

This means that only 37% of our area is in the general routing, and 63% is inside the logic
|
||||
block. Note that the crossbar / local interconnect is considered part of the logic block
|
||||
area in this analysis. That is a lower proportion of of routing area than most academics
|
||||
assume, but note that the total routing area really includes the crossbar, which would push
|

routing area up significantly, we estimate into the ~70% range.

the 4 inputs of fracturable LUT4 are no longer equivalent,
