Protel
Applied Simulation Technology interfaces with the Protel PCB environment through a translator called PL2AAIF. The translator works by accessing the Protel ASCII PCB data and converting it to Apsim’s AAIF format. The AAIF file can then be displayed by ApsimTOPOL. ApsimTOPOL servers as the front end to the Apsim tool suite. The AAIF format is used by all of Apsim’s application software tools for Signal Integrity, Power Integrity and EMI simulation.
Protel to Apsim CAD Interface
Protel to Apsim CAD Interface Usage
Protel PCB .asc file is needed.
The interface program pl2aaif is used to convert the PADS data into Apsim AAIF or AIF.
The converted AAIF or AIF format is a text based description of the CAD data.
Apsim’s AAIF or AIF data is used by all of Apsim’s application software to model and simulate the design.
ApsimSPI is a future product which is announced but not fully released.
The interface is a one way only.  Any interactive changes are made with the Apsim application software.
