I think it's more of a reference book than a teaching guide, but very well written and with good examples. Keep in mind that it covers VHDL as a language, and there are a lot of things you can do in the language which won't work for synthesis (VHDL was designed for simulation after all). It's still possible to get 5V tolerant CPLDs, e.g. the Xilinx 9500LX series, but not so for FPGAs (or they will be old designs and very expensive). So as Ruud mentions, logic level shifters are unavoidable. Regards, Laust Message was sent through the cbm-hackers mailing listReceived on 2012-06-07 20:00:36
