Hi @Leonardo Gomes I know you had some very nice work on EM simulations using IHP PDK and have a modified script for gds to matlab conversion for SKY130. Do you happen to have a SKY130 matlab script for actually running the EM simulation? I am specifically looking for the SKY130 material stackup information. If I can find this information I can adapt it to matlab script format that openEMS understands Here is that particular code section for IHP130 for a few of the layers.
