ANSYS just released v2014 of ALinks and SIwave. This adds another option for importing Cadence Allegro, APD and SiP:
If you have the following situation then you can directly drop and drag .brd, .sip, and .mcm into the SIwave GUI using SIwave v2014. Alternatively there is a File->Import Cadence from within SIwave too. The .anf and .cmp export or SIwave launch still works as well.
1. Have Cadence Allegro, APD, or Sip installed on the same machine as:
2. ANSYS ECAD Translators v8 (released Dec. 2013)
3. ANSYS SIwave v2014 (released Dec. 2013)
Again the traditional export .anf and .cmp from Cadence still works to. You can still launch SIwave from Cadence too.
