#122590 - Skahill's VHDL book Responding to: ???'s previous message |

There's a book written by a fellow at Cypress that tries to serve as a VHDL text, but the main benefit of which is that it goes into considerable detail in describing the salient features of various manufacturers' devices. It shows the advantages and disadvantages of CPLD's, for example, as contrasted with FPGA's, and goes on to describe, at least in part, the advantage of ACTEL's structures and those of XILINX's. The author's name is Kevin Skahill, I believe. The one thing you must keep in mind when reading this book is that he worked for Cypress at the time, and they made CPLD's and not FPGA's. And the book is horribly out of date. One problem was that Cypress' VHDL synthesis tool was barely VHDL-87 compliant and by 1997 when I looked at it, most of the FPGA synthesis people (with the exception of Synopsys) had finally implemented the relevant parts of the VHDL-93 spec. In other words, this book isn't the one you want if you're learning VHDL. Ashenden's book is real good although it doesn't have much of anything on synthesis. -a |
