* **pn_ratio:** specify the ratio between p-type transistors and n-type transistors. The ratio will be used when building circuit structures such as inverters, buffers etc.
* **pn_ratio:** specify the ratio between p-type transistors and n-type transistors. The ratio will be used when building circuit structures such as inverters, buffers, etc.
* **model_ref:** specify the reference of in calling a transistor model. In SPICE netlist, define a transistor follows the convention: <model_ref><trans_name> <ports> <model_name>. The reference depends on the technology and the type of library. For example, PTM bulk model use “M” as the reference while PTM FinFET model use “X” as the reference.
