Hi, Could someone who is familiar with Cadence's Specific-Driven Environment help me with these problems that I have been encountering. I'm trying to learn the Characterization and Modeling Environment (CME) feature by trying and following the tutorial that is included in Cadence's documentation. I ran into two problem, when i clicked on "Generated and Run" in the "Spectre VCME Setup" I kept getting error messages that complains about the models in basicModels.scs (npn and pnp) are bein redefined and VSdE session is terminated. I have set enviroment setting for ACV_ROOT and ACVDEMO. Also, what are the difference between the dcmui and verui files. In the "Spectre VCME Setup" window, I found out that the verui has alot less setting (e.g., the Verilog settings are missing). thanks!
