variables: add OPENROAD_HIERARCHICAL

[oharboe]

Quick test:

make DESIGN_CONFIG=designs/asap7/aes/config.mk SYNTH_HIERARCHICAL=1 SYNTH_MINIMUM_KEEP_SIZE=0 OPENROAD_HIERARCHICAL=1 clean_synth synth do-1_3_synth

Recall: do_1_3_synth creates a .odb file

Now run in GUI:

make DESIGN_CONFIG=designs/asap7/aes/config.mk SYNTH_HIERARCHICAL=1 SYNTH_MINIMUM_KEEP_SIZE=0 OPENROAD_HIERARCHICAL=1 gui_synth

@maliberty Fixed crash by adding the missing -hier option to open.tcl. I guess read_db shouldn't crash in this case...

I tried write_verilog: I got many modules for:

make DESIGN_CONFIG=designs/asap7/aes/config.mk SYNTH_HIERARCHICAL=1 SYNTH_MINIMUM_KEEP_SIZE=0 OPENROAD_HIERARCHICAL=1 gui_synth

[maliberty]

@precisionmoon @jhkim-pii FYI for testing -hier by itself

[oharboe]

@maliberty merge manually? I think the errors are unrelated to PR
