kareem 7c524edd31 openlane(wip)!: housekeeping 
~ fix typo in referencing variables in sdc file
~ fine tune parameters to get the design to route
with cts and diode insertion

!important:
depends on SAVE_LIB patch from openlane

kareem acf92c3460 views: update gpio_control_block gds 2022-09-27 07:42:32 -07:00
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

kareem c1e0d5ba06 openlane!: reharden gpio_control_block 
update gpio_control_block config for new openlane versions:
- disable `SYNTH_BUFFERING` and `SYNTH_SIZING` to limit the design size
and fit the floorplan
- change `SYNTH_STRATEGY` to `AREA 0` to minimize design cells
- disable `PL_RESIZER_TIMING_OPTIMIZATIONS` and
enable `GLB_RESIZER_TIMING_OPTIMIZATIONS`
- remove `FP_IO_*` and replace them with `FP_DEF_TEMPLATE` for io placement
- set `DECAP_CELL` to not use ef decaps.. i think that was for simulations?
- enable some turned off `QUIT_*` variables
- replace deprecated variables such as `GLB_RT_*`
- customize `pdn.tcl` to force pdn straps to follow the old pattern
- replace `$script_dir` with `$::env(DESIGN_DIR)`

!IMPORTANT - still need to run dynamic simulations

issue-105: caravel & caravan.mag: relabel top-level v*_core power nets (label PLUS underlying met5); (#110) 
tweak blackbox lvs scripts for very fast extract; update spi/lvs/*.spice.
The .spice (once propagated to caravel-lite AND caravel-lite embed in mpw_precheck docker)
will pass the consistency check.
