kareem 285ef6b642 reharden!: caravel
~ update the following views:
def
mag
verilog
spef(all corners)
+ add the ability to override the interactive script filename
+ add the ability to run openlane regression using regression.config
file
~ change GRT ADJUSTMENT values
~ change pointers to some files for workarounds

!important the interactive script still needs updates
!important this was done using old openlane v0.22 and its matching
pdk
!important known workarounds:
- a custom techlef is used where large metal spacing rules are the
only ones present to avoid violations by the router
- some odd behaviour happening when a macro has a lef view
with a non zero origin. so the power routing cell is (temporarily)
modified to have a zero origin and its placement has been shifted
which doesn't match the power routing mag.
- the old openlane doesn't generate multi spef corners. they
are generated using timing-scripts repo

kareem 85f7f86c4e reharden!: gpio_control_block
- high level changes:
* add larger buffers on output ports
* add buffers on input ports
* adjust sdc file increasing output load and setting a high transition

- detailed changes:
* add interactive script for openlane where the order of events is a bit shuffled
	- to add obstruction before pdn
	- to manually insert buffers on some ports
	- to manually remove buffers inserted by synthesis on for example serial_clock_out
* change openlane config adding extra row and columns to increase the space and fit the
added buffers
* change config to enable buffering
* increase density for better placement?
* change the cell exclude list. some excluded cells didn't make sense
* ef decap cells break dynamic sims?
* add custom pdn script for to duplicate the old pdn

- misc changes:
* fix openlane makefile to properly detect interactive script

!important still need to run dynamic simulations
!important depends on some updates to openlane

Fix upstream breakage due to missing docker mount (#80) 2022-04-21 05:34:37 -07:00

Caravan top lvs (#67)
* - update caravan configuration
* change correct gpio_default blocks instance names
* implement powerrouting work around
* place spare logic blocks
* keep the history of runs and sym link last/final one

* - update caravan mag, def and gl views
- add fake power routing cell in the rtl as a placeholder for openlane
  to prevent routing on that cell
- fix some syntax errors in chip_io_alt
- match simple_por lef pins with mag by regenerating it

* Apply automatic changes to Manifest and README.rst

* add caravan power routing lef

* - update mag and def view of caravan
- add_macro_placement for fake cell

* Added back the power routing to Caravan, fixed DRC errors, ran LVS,
corrected placement of isolated substrate regions, and replaced the
signal routing for the analog lines.  Be aware that merging with
main may cause issues with the mgmt_protect.mag file and its
subcells mprj2_logic_high.mag and mprj_logic_high.mag.  It may be
worth cherry-picking the files to merge and exclude those layouts.

kareem 449cb47360 fix comment typo 2022-02-25 10:47:04 -08:00
kareem 0f04a43f58 - change litex tag to mpw-5c
- warn before deleting when rerunning these targets:
    install_mcw openlane pdk
- clone litex with depth=1 and single branch
- simplified pdk targets by removing these targets:
    skywater-timing build-pdk skywater-library
- add clean-pdk and clean-openlane
- add make prerequisites in pdk (not sure if that's needed)
- run openlane docker non interactive
- export OPENLANE_IMAGE_NAME when running openlane docker
- add check-openlane-env target

Donn 89629b357f Change `make openlane` to `make pull-openlane` in the OpenLane Target

Also, add pdk-with-sram target.
