As I remember, with earlier versions, I can always import an asc file generated as layout netlist to an existing design. Or in other words, I can add something to an existing design through import function. But with PADS V9.1, it will generate an error message each time when I try to import something: "Fatal Database Error Number 2012, Invalid Database Object Type. Please read the online help topic. Recovering from database problems". The the program will crash.
I could not find any information on Error Number 2012. Does anyone know how to solve the problem? PADS 9.1 works on earlier files with this import function.
Thanks in advanced
