Hi Tom / Gerhard / Magnus et all.

I have been using Altera parts, primarily because the finished boards on
*bay are so cheap.
I'm still a beginner in VHDL , but can do a little ....


I have both Xilinx ISE & Altera Quartus installed on my linux mint 17
(x64) , and both works ok.
With a few install quirks.


VHDL is quite the same for both , and only the timing constraint magic
is different.

Gerhard would'nt a 240 MC 7$ cpld board , or a small 14$ FPGA be a nice
base for some of your timing magic ?
