- houli 11y agoYep my computer architecture class used the same tools. It's only been 2-3 months since but I'm already having painful memories of the syntax errors and nights of staring at red "UUUUUUUU" undefined registers.
- baldjinx 11y agoI agree that the Xilinx tools are not so easy to use, but I feel that they are far from painful. I am amazed with the functionality of the free version of ISE (both in simulation and floor plan design). I have used this software to prototype and implement a 3rd order pipelined sigma-delta modulator on a FPGA, and several simple CPLD projects which didn't require simulation. The simulator is far from crippled. I was able to read input from a binary test vector file into the simulator, run it though the model, and save the output to file. I found this very useful during development to compare the VHDL implementation with the prototype I had written in C.
