Hello everyone.
I tried openlane + caravel flow with simple RTL.
But 1 LVS error happened.
Could you teach me the root cause and countermeasure?
〇Structure
+ user_project(Logic)
+ memory (sky130_sram_1kbyte_1rw1r_32x256_8) x 1
〇RTL
- user_project_wrapper has only connection.
- user_project has some small logic to write/read memory.
〇config
- setting.png has json data.
- user_project_wrapper and user_project RTL are synthesized simulteneously.
〇Error
- LVS error happed in signoff phase.
- They are in openlane.log.png and 29-lvs.lef.log.png.
