Mapping GENESYS Substrates
When a GENESYS schematic is exported to ADS, a substrate is inserted onto the ADS schematic if any component needs it. The ADS substrates supported during schematic export are:
- CPWSUB - Coplanar waveguide
- MSUB - Microstrip
- MLSUBTRATE2 - Multi-layer substrate
- SSUB - Stripline
The substrate parameters are mapped as follows:
