Protel98 and PLDs

[Sticks]

Hi All ,

Has anyone had any experience in designing a PLD directly from a
schematic
diagram using Protel 98 .....
Have used Protel for schematics and autorouting creating footprints etc
and in the process of trying to learn more in the sch/pld area
Libraries provided for PLDs and symbols seem to be a bit light on .

I was able to design PLD from an example schematic given , also to
design
another although extremely simple logic with a couple of AND gates
just to see if i could get it to work.

Any ideas or pointers to some online help would be appreciated
or are later Protel versions more efficient in this area .

thanks

What pld are you using ?

pla, pal, cpld, fpga ?

Which manufacturer ?

Does the manufacturer of the pld provide free software ?

If its an older pld can you use one of the free software packages ?

Using GAL20V8A and possibly PAL series
, have no problems using WINCUPL to write code and then
program the chip , but i am trying to basically do the
same but directly designing from a schematic diagram
in Protel , they have been using ORCAD but i think
thats a bit outdated and besides i have not used it before

I like the ICT-Place program and their PEEL22CV10Z (or somehting like
that). The program is the easiest to use I've ever run into. The DOS
version was better than the new Windoz version. For some silly reason
they left the text search out of the Windoz version.

Unlike other programs, you click on the picture of the macro-cell until it
lookes like the type of circuit you want. Once you've got the right sort
of flip-flop, you then write the equations for what goes in.

I find that the schematic library for PLD that came with the Protel 98
really limited and ended up writing it in CUPL to make it work in the end.
