FABulous-SKY130

This repo experiments the openlane design flow for a small fabric generated by FABulous framework.

Notes

• Please place the folder under openlane/designs directory
• Use the following commands to run the flow

  $ ./flow.tcl -design fabric4

Issues

• The openlane flow can run succesfully for the fabric22 (2x2 CLBs) but get stuck when doing global routing (fastroute) for the fabric4 (4x4 CLBs).
• Timing Optimization step by OpenPhySyn (for nestlist) was skipped due to unsupport set_timing_disable command (like the STA tool).
