what is the difference between the Orcad 16.5 to Allegro PerformanceOption - L V16.5?
are the designs convertible from Orcad to Allegro and vice versa? Since both are cadence softwares.
No. You used to be able to translate Cadstar (CDI) to OrCAD Layout (max) which was the old PCB tool. It's not avaliable now unles you have an install of 16.2 or older. The process would be Cadstar CDI to MAX then MAX to Allegro BRD.
