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.

manarabdelaty aa766f9144 [DATA] Update caravel_clocking module 2021-12-05 19:44:28 +02:00
Tim Edwards 3246e64407 Correction to the gen_gpio_defaults.py file, which was accidentally
overwriting the top-level gate-level verilog netlist with the
modified layout file contents.
2021-12-04 12:41:06 -05:00
Tim Edwards 9da6bab4a8 Corrected DRC errors on the non-Manhattan edges of the caravel
and open source logos.  Modified the gpio_defaults_block layout
so that open holes are not created in the metal1 when the vias
are moved by the defaults block configuration script.
2021-12-03 22:21:06 -05:00
Tim Edwards bd6af6dddc Modified all of the Makefiles to better handle the GL netlist simulations,
which is now done through setting an environment variable to point to the
location of the management SoC wrapper.  Added the missing user project
wrappers to the GL directory (copied from the original caravel repository),
and also the GL version of chip_io_alt.  Modified the caravan_netlists and
caravel_netlists files to import the correct list of gate level netlists,
which has been reduced by moving "include" statements for components of the
management SoC into the management SoC repository (e.g., caravel_pico).
2021-12-03 17:13:53 -05:00
Tim Edwards b23ec956f3 Corrected the mprj_bitbang testbench verilog (it had not been corrected for
the change in the implementation of the serial loader, which split the load
signal out as a separate bit, and therefore had a separate bit-bang entry).
2021-12-03 15:06:15 -05:00
Tim Edwards 2691903104 Reworked part of the layouts of both caravel and caravan to move
the clocking subcircuit from inside the pad area near the "clock"
pin to under the DLL.  This prevents the DLL from having its
outputs travel all the way across the chip to reach the clocking
cell and then have the multiplexed clock travel all the way back,
especially as the DLL outputs are high-speed signals (up to 150
MHz).
2021-12-02 20:45:39 -05:00
Tim Edwards 024801ab56 Extended the gen_gpio_defaults.py script to handle modifying the
verilog gate-level netlists to match the correct GPIO default
value assignments, and modify the top level gate-level caravel.v
and caravan.v netlists to match.

Tim Edwards 4cf7aa2983 Changed the synchronized reset to occur on the clock falling edge
to give more timing margin when reset is released (note to self:
shouldn't the ext_reset also be synchronized?).

Tim Edwards 6482c1e011 Corrected the set_user_id.py script to (1) reverse the position of
characters in the user_id_textblock layout, which was backwards,
and (2) add a path reference to "hexdigits" for each new character
layout encountered in the file, so that the text block layouts
are found even if "addpath hexdigits" has not been specified.
There were some other corrections to handling gzipped files that
probably does not apply in practice, where "make uncompress" has
been run prior to the set_user_id.py script.
