I encountered an error while attempting to simulate the 'tb_reram.sch' file in the Sky130 B process. Could you kindly provide guidance on how to troubleshoot and resolve this particular error?

Try searching for

in slack. There are several threads such as https://open-source-silicon.slack.com/archives/C02Q2DE33QF/p1658901757680079
