I am looking for a reasonably priced front-end toolset for VHDL multi-vendor FPGA design. This should as a minimum provide:
- VHDL design entry (text based and high level graphical)
- Functional simulation (testbenches with file I/O)
- Post-synthesis and timing (post-PAR) simulation.
For this I am considering ActiveHDL, but since we also do a lot of hardware design using the Protel schematic and PCB tools, the new nVisage DXP version with integrated VHDL front-end tools looks interesting. As anybody used these tools in nVisage or DXP and has any opinion on their maturity, features and quality?
