virtuoso schematic replace function

Hi everyone! I’ve run into a tricky problem, as follows: I need to replace all the CMOS in the schematic with CMOS from another process technology. However, when using the “replace” function, the default values of the device parameters in the new process CMOS overwrite the parameters of the devices to be replaced. How can I solve this issue?

I’ve searched for some solutions before, such as loading a mapping file when using the replace function to declare that the parameters remain unchanged. But there is no option to load a mapping file in the “replace” function window. Is it because the version of Virtuoso I’m using is too old? Besides this, are there any other methods?

Best regards

Migrating from one technology to another is not necessarily straightforward. The result you see is typical. Additionally the parameters may not even map to parameters of the same name. e.g. You might find 'fingers' or 'nf' and sometimes even 'm' mapping to what is the number of poly fingers/gates. Hence you really need to migrate with some mapping information. Cadence does offer a tool for this purpose. Please see...
