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 |
