#1486 Crash in floorplanning when using asap7 Issue created by yupferris Description When attempting to use the flow on any design using asap7 (using this version of volare to install/activate as well as #1484 and #1485), I get a crash in

openroad

when floorplanning tries to insert tie cells. To reproduce: 1. Use a local volare build with this patch to enable asap7 support and build/enable the PDK

volare build -j$(nproc) --pdk asap7 --clear-build-artifacts --sram -l all 1967b4b2eb2c32b33f948bad4891b8cebd0107f0
volare enable --pdk asap7 1967b4b2eb2c32b33f948bad4891b8cebd0107f0

Note that the hashes here simply refer to the latest commit in the

OpenROAD-flow-scripts

repo. 2. Try to run (any) design through the OpenLane flow

PDK=asap7 STD_CELL_LIBRARY=asap7sc7p5t STD_CELL_LIBRARY_OPT=asap7sc7p5t ./flow.tcl -design gcd

Expected Behavior I wanted to get a simple design through the OpenLane flow using asap7 (or at the very least, past floorplanning, where I could continue to debug further issues I may encounter). Environment report
