Could you recommend GAL synthesis software? [slightly OT] |

Colleagues,
I have to support a legacy circuit, which has a GAL chip in it. I have the VHDL code for it, but I don't have the binary. I'm looking for the software (preferrably for Windows, preferrably free), which can compile VHDL code into a downloadable binary. What would you recommend?
Sincerely,
Nick |

GAL SYnthesis |

Your best bet is to go to the manufacturer's web site. Most of the manufacturer's I am familiar with offer some form of free synthesis program for their chips, at least the low end stuff like the GALs. If it is a Lattice GAL, I know their ISP software is downloadable. If the manufacturer you deal with wants to charge you something, just make nice with the rep, tell him about the millions you plan to order and you can get it for free.
Good Luck

There are many sites/forums/posting on this issue. (have you tried to google for 'VHDL freeware' ?)

I have downloaded the ispLEVER and Synplify. As far as I could understand the Synplify is a synthesis tool, which generates the EDIF file, and then ispLEVER does the fitting and produces the JEDEC file. The problem is that the GAL is not in the list of the technologies supported by Synplify. (There is ispGAL, but the plain ol' GAL is not in the list.) Is there a workaround? |
