Tim Edwards ccd0a19af7 Organized the documentation, corrected and extended the entries. The original 
datasheet has been broken up into individual pages;  these can be recast into
sphinx or HTML as needed, while the graphics have been exported to SVG.

manarabdelaty 92f1ab7ace [DATA] Update chip_io_alt.gds to match the mag view 2021-12-09 22:15:05 +02:00
Tim Edwards ec93c72d18 Modified simple_por.v RTL to avoid the wire declaration that "cvc" 
doesn't like (even though it's perfectly legal).
 2021-12-08 12:16:19 -05:00
Tim Edwards b9fdac94ff Corrected a typo in the run_chip_io_alt_lvs.sh script. 2021-12-08 10:06:50 -05:00
Tim Edwards 75f4e49a99 Removed two floating metal2 rectangles from chip_io_alt. 2021-12-08 10:00:57 -05:00
manarabdelaty 2aa61e7bff [DATA] Update gpio_control_block gds to match the mag view 
- now has the substrate cut layer for isolating the two ground domains and passes LVS on the gds
 2021-12-08 15:14:04 +02:00
Tim Edwards 8cac89ec74 Changed the user project wrapper and user analog project wrapper 
to be abstract views, and modified the LVS scripts accordingly
(they no longer need a special version of the netgen setup
script).  LVS was verified on both caravel and caravan using this
setup.
 2021-12-07 22:21:49 -05:00
Tim Edwards 489bddcf98 Two more changes: (1) Correction to chip_io_alt.v RTL verilog to 
match what was done earlier on chip_io.v, and (2) Corrected a
set of four labels in chip_io_alt.mag which had been rotated,
causing an error in LVS.
 2021-12-07 17:16:44 -05:00
Tim Edwards 624317bc3f Corrected the missing port designation on porb_h in chip_io.mag 
and chip_io_alt.mag.
 2021-12-07 12:38:18 -05:00
Tim Edwards 79828c00b3 Revised the LVS run scripts to use $PDK_ROOT instead of a hard- 
coded path.
 2021-12-07 10:32:22 -05:00
Tim Edwards c3fc004072 Corrected an error in verilog/gl/chip_io_alt.v, which was missing 
connections to the core side VCCD1 and VSSD1 on the clamped3 pads.
Also added scripts for running LVS on chip_io to the mag/ directory,
and revised the scripts so that they will only re-run extraction if
there is no netlist file in the mag/ directory.
 2021-12-07 10:06:35 -05:00
Tim Edwards a6d9dbf535 Corrected an inadvertant error in caravel_netlists.v that prevents 
gate-level simulations from running.  Corrected caravan_netlists.v,
which did not have the same change made yesterday to caravel_netlists.v
for the DLL.

manarabdelaty 95b30f6eca Update caravel_timing target 2021-12-07 13:01:40 +02:00
Tim Edwards d4b4b7abb8 Fixed one bad error in clock_div which had been done without my 
knowledge and which went undetected since before MPW-one.  Modified
the "pll" and "sysctrl" testbenches so that they run and measure
something useful.  Both exercise the clock monitoring on GPIO
outputs functions.  The PLL test also runs the digital locked
loop (behavioral verilog).  The PLL test overlaps sysctrl, but
"pll" cannot be run on gate level verilog, whereas "sysctrl" can.
 2021-12-06 21:37:51 -05:00
Tim Edwards a9bb8bcd0a A handful of changes/corrections: (1) Housekeeping signal "user_clock" 
(input for monitoring) changed from being connected directly to the
user project (where it shouldn't be) to the same signal on the input
side of the management protect block (where it should be).  This is
functionally the same.  Checked for any other signals connected
directly from the user project to any block other than mgmt_protect,
didn't find any (good).  Modified the gate-level netlists and top-level
layouts for caravel and caravan with the corresponding change.  This
was the only change affecting layout.  Also:  Revised the "pll"
testbench.  This is still ongoing work.  Also:  Fixed the way the
pins on I/O pads are declared in chip_io.v, mprj_io.v, and pads.v, so
that it isn't so bizarre.  Most of this change is functionally
agnostic (just a change in the way the ifdefs work), but did fix an
incorrect ifdef that causes the whole user power domain to be broken.
