New ContributorI'm fully aware that the part is now obsolete, and nothing would be better than using new parts and up to date software, I totally agree with you there.
I have used the filters of several parts distributors I can easily order parts from (mouser, digikey, farnell, rs, elfa and so on) to try and find available CPLD's with at least 160 I/O lines, 7.5ns or better, and suitable for 3.3V/5V environment and a package that is not a BGA, very little is left.
Digikey offers the EPM7256AQC208-7 as a Rochester marketplace product, and the same part is also available from several sellers on Ebay at much lower prices.
Although I have access to a production line where BGA is possible, this is for a hobby project, so at least I would like the first version to be hand solderable/reworkable, although I might switch to an BGA incarnation later on if I get it working, unless I need heaps of level shifters.
3.3V I/O support would be mandatory.
ContributorYep, I hear ya. Support for 3.3V I/O is still fairly common in modern devices, but long gone are the days of 5V-tolerant I/O and of hand-solderable QFP packages.
To your original question, I did a quick search and came across the thread below. You could try the solution described there of hand-editing your QSF file and see if Quartus 13.0.1 accepts your p/n that way:
New ContributorThanks, I will check it out!
