For the evaluation board MCBx51, a GAL is used to do some combinatorial logic. I could read somewhere that palasm4 of AMD has been used to 'compile' this. A search on the internet gave me the idea that this is a very old compiler (can I say it like this?). It looks like it's an "early 90's" program (I saw many times release 1.5a from '92). However, I couldn't find the program itself. Does anyone know if that still can be downloaded somewhere and if some info is available? Reason for asking: I want to understand a bit the programming syntax of such device and try to experiment with it. Best rgds, --Geert
PALASM seems to be available at: http://www.engr.uky.edu/~melham01/ee481/software.htm Reinhard
Thanks for the info, Reinhard, Best rgds, --Geert
The manual in that freebie PALASM is dated (!) 1993. AMD hasn't been in the PAL market for years. Lattice took over AMD's logic subsidiary in 1999: http://www.latticesemi.com/corporate/press/corporate/1999/pr042199.cfm Unless this is for a specific historical interest, don't waste time with it. Here is the current Lattice CPLD product page: http://www.latticesemi.com/products/cpld/index.cfm I think you will find that Lattice, Xilinx, Actel and the like all have a wealth of free learning materials on their websites.
Unless this is for a specific historical interest, don't waste time with it. Hi Andi, It's not really for a historical interest, it's more to know what I have to do if the GAL of the MCBx51 board has to be upgraded for one reason or another. I've seen somewhere on the site of Keil that there is (was?) already an update posted and I just wanted to know what the 'syntax' was that is used in the --indeed-- very old language. But I will definitely not waste my time with this. Best rgds, --Geert
