There is a Specctra interface available for Easy-PC, this provides a bi-directional link to output the initial design to Specctra, and read the routed results back again afterwards.
The UK price for this is currently GBP97, please contact sales (sales@numberone.com) if you wish to purchase this link.
I have spectra & Cadence full tool, but I like to route in Easy-Pc since I am using this tool from the old DOS version to the latest V13 & many of my customer using Easy-Pc asking EMC & SI varificatoin.
If I can transfer Easy-Pc file, it has provision to export to SI tool .
If you can email a suitable PCB design file to info@numberone.com with a message explaining that its FAO development, we can certainly generate a test DSN file for you.
