I want to test Altium Designer a possible replacement for Mentor DC / Expedition.
Altium can't translate DC. They can translate DX but not the current version. Only versions
I am Mike Gibling working in Mentor Graphics Customer Migration Team (CMT), I have worked together with a number of customers who have successfully moved from DC to DxDesigner and are productive, please let me know if I can assist you with guidance in the translation of library & designs as you consider the move to DxDesigner or help with any general questions you may have.
