I have been looking for a cheap ChipScope. I could not find any open source and I would love to hear if anyone is working on something.
I tried the evaluation of TopJTAG and it worked perfectly - just like the video. I made a simple Sparten3E evaluation board with platform flash. I was running it at 10MHz with a BusBlaster 2.
Anyone else tried TopJTAG yet? It is a little steap for a hobbyist ($100). I am unable to link to the site since this is my first post.
I will continue to evaluate and will decide later if I should buy it for $100.
Someone released an open source chipscope-like thing in the forum somewhere here.
