Jeff DiCorpo de041996a6 Merge branch 'main' of https://github.com/efabless/caravel_openframe into main 2021-12-01 17:27:24 -08:00

Tim Edwards 0f90c813ed Added a missing route that was not completed in the previous layout 
update.  Also changed the defaults block types in the layout so that
they match the gate-level netlist.  This does not change the behavior
after assembly but lets LVS run correctly on the layout prior to final
assembly.

Tim Edwards e0a318d2bf Fixed the GL verilog for caravel and caravan to add the two changes 
just made to the RTL verilog and layout, to separate out hk_cyc_o
and to hook up the housekeeping user_clock input.
 2021-11-30 12:31:07 -05:00
Tim Edwards 1035e8b469 Updated caravel and caravan layouts to reflect the simple change 
to housekeeping and the management core wrapper to separate the
wb_cyc_i signal and connect to new signal hk_cyc_o on the
management core.  Also:  Fixed a dangling input (user_clock) on
the housekeeping (minor error caused by the earlier refactoring
and unnoticed because there is no testbench covering that
function).

manarabdelaty c4efcec989 [DATA] Update housekeeping views 2021-11-30 13:00:33 +02:00
Tim Edwards 4c0a2303b1 Modified the GL netlists to match the layout for the GPIO defaults 
blocks;  that is, there are special versions of the block for the
first 6 GPIO pins.  That should allow the GL netlists to simulate,
although the end goal is to have the gen_gpio_defaults.py script
modify the GL netlists to exactly match the configuration, as is
done for the .mag layouts.
 2021-11-29 20:17:11 -05:00
Tim Edwards 84c97b74b2 Corrected the instance names in the layout so that they once again 
correspond to what the script gen_gpio_defaults.py is looking for.

file, which shouldn't be there.

Tim Edwards cd4a052344 Made the same change to caravan as was made to caravel in the 
last commit.
 2021-11-29 14:27:02 -05:00
Tim Edwards 4dac106297 This (late and invasive) change modifies the housekeeping block to 
add a separate signal for the houskeeping wb_cyc_i wishbone signal,
instead of combining it with the user project's wb_cyc_i.  This
change makes it compatible with the LiteX implementation of the
wishbone bus.

Tim Edwards e2ee74c591 Changed "simple_por" in both caravel and caravan to be an abstract 
view pointing to the contents of ../gds/ so that when the assembled
chip's GDS is generated with "cif *hier write disable", the POR
will continue to have the GDS with the proper hierarchical processing.

Tim Edwards f67f7b6daf Corrected bad paths on two layouts in mag/ and most of the layouts 
in maglef/, all of which were erroneously pointing to paths in
either OpenLane or the user's home directory path.

Tim Edwards fe21089505 Updated caravan with the same addition of four spare logic blocks 
as was made to caravel.
 2021-11-24 17:10:05 -05:00
Tim Edwards be98da0fe6 Added spare logic block to caravel layout and verilog GL, wired 
it to the power supply, and checked top-level LVS.

Tim Edwards 543fee18e3 Revised the spare logic block to make sure that all inputs are 
reachable from pins on the boundary once it's synthesized.
 2021-11-24 09:34:52 -05:00
Tim Edwards 2b156997cb Added a new module with "spare logic" for metal mask fixes. 2021-11-24 09:23:22 -05:00
Tim Edwards 9b1a18a15e Finished drawing all of the analog connections to meet cleanly at 
the user analog project boundary.
 2021-11-23 17:32:52 -05:00
Tim Edwards 0114df40ae Added additional power routing from the sides of Caravel to the 
user project power ring.  If that is incompatible with user
projects and/or the XOR check, then this commit might need to be
reverted.

Tim Edwards 0ba8884b00 Added a motto for each chip. Just because. 2021-11-23 15:19:41 -05:00
Tim Edwards 1ff48245e8 Pushing final layout of Caravan, now LVS clean. 2021-11-23 14:06:14 -05:00
Tim Edwards 5d3f2a26f4 Corrected the Caravel layout and the Caravel and Caravan GL netlists 
to resolve the problem with the typo that caused the propagated
GPIO serial load, reset, and clock signals to get scrambled on the
user2 side.  Caravel is now LVS clean again (Caravan needs layout
work).
