My most important problem is software. In my university department, there hasn't been any IC design tool for the present. For my undergraduation thesis i need someones. As i said before, i decide to design microcontroller. Seemingly, i must choose FPGA releases . I haven't used already. So i don't know without implementation it can be sufficient or not.
At first, i considered asic desing tools, but i haven't found any cheap one yet. So I will download and try QuartusII web edition.
regards,
