@User I'm attempting to run device level LVS on the caravel chip_io block. caravel

origin/develop commit 384a7d517a82c49a0c4411c8132ce3f97eebfad5

Using magic 8.3.123 Here's a sample of the extracted netlist. The ports are strange and not connected to any instances.

To recreate the netlist, go to

caravel/openlane

and run

gunzip ../gds/chip_io.gds.gz
flow.tcl -design chip_io -tag ext -lvs -net ../verilog/gl/chip_io.v -gds ../gds/chip_io.gds

The extracted netlist will be in

chip_io/runs/ext/results/magic/chip_io.gds.spice

Also having trouble extracting DFFRAM. Here's the top cell.

You can see that the power is all unconnected. I was getting close to clean LVS runs on DFFRAM back in December.
