Hi,every one.i want to know if there is any plugins for Altera processors? i got a programe from the rom of ep1c6q240, but the IDA can not dissamble it rightly.
TKS.

Quick answer - No IDA does not disassemble FPGAs.

Long reasoning...

FPGAs are not general purpose processors and as such, reverse engineering them is extremely (and I am being mild here) complicated.  

IDA Pro does not currently, nor would I necessarily, look for it to ever have a processor module to disassemble an FPGA.  Partially for the fact that an FPGA is simply a complex combination of gate logic and as such how would you represent this in IDA?  Transferring the gate logic back into something like VHDL is perhaps possible, but adds a ton of additional complexity.

The only note I'd add is that Altera licenses the Nios and Nios II processor cores for its FPGAs. To my knowledge, no processor module exists (publicly, at least) for this CPU; however, the instruction set is well-documented by Altera, so creating such a processor module would not be terribly difficult. I wrote one for a different core in about two weeks a while back, just to give you an idea of the level of effort. YMMV!  ;-)
