i want to implement some logic functions in only one chip.
how can i programm GAL 16V8-25QJ?
is it possible to write the code in vhdl?
which tools are needed for this?
Hi abba ..
The best way to programm those chips is by usin a low level language
like PALASM , CUPL , ABEL or PLDSHELL from intel
You can always use VHDL .. but is an OVERKILL and if you are not familiar with the GAL architecture .. you will get lost in the language ..
or will not be able to optimize the design !
But don't blame it on the language or on the tool , is your code .
this week i bought two peaces of 'GAL 16V8'-because they are cheaper and smaller than xilinx cpld's (costs about 2$).
I think to program this device in abel.
For my circuit following gatters are needed (I hope it's possible to implement this):
4xNOR
8xNAND
1xInverter
At the next step i'm searching for:
-little example in abel
-simulation tool
-compiler (abel2jtag)
-small circuit for programming GAL by LPT-port.
is it possible to work with the xilinx project navigator?
(
source programming with Project Navigator,
simulation with ModelSim,
GAL programming with iMPACT
)
search in elektor electronics magazine site b'cos i remember once they had given a project regarding gal programmer with details regarding the tools used.
Hi
Go to lattice web site. https://www.latticesemi.com/
Download ispLEVER software package.
First, choose the right chip.(e.g. with enough I/O ports; ispGAL or GAL)
Then,
i) write your code in Modelsim(VHDL code compiler).
ii) Feed your code in ispLEVER, compile it, it'll generate XXX.jed file.
iii) Feed XXX.jed file in ispVM, if you have the download cable and the programmer, then the rest is as simple as click a few buttons.
Yes. My favorite tool is Cypress WARP. You can get it at DigiKey, or from Cypress directly (together with a descent VHDL book, if you need it) for $99 (428-1303-ND). It's also downloadable (the keys are out there).
