Title: no-ideal amp compling errors
Post by westwind on Jul 19^th, 2007, 11:30pm

I'm using the non-ideal opamp model from AHDL library in Cadence. The code is the same as one posted by hchanda: http://www.designers-guide.org/Forum/YaBB.pl?num=1165362179/5#5.
when I compling this code, It gives me some error like " ERR732 [73:7]: Input port 'vref' can only be probed." I do not
understand this, could anyone help me, thank you very much!

A current is assigned to the vref port although it is only declared as an input port. Declaring it as an inout port will probably fix the problem. The compiler seems to have improved its checking, breaking old non-compliant code in the process.
