<u>II.2.5 How to Program GALs</u>
After the GAL-Assembler has created the <a href="jedecfile.html">JEDEC file</a> from the <a href="sourcefile.html">source file</a>,
the GAL can be programmed using this JEDEC file. To initiate the
programming of the GAL, simply select <a href="menprog.html">Program</a> and give the JEDEC file
name. As soon as the GAL is programmed, a requester pops up, and tells
you the GAL is programmed, and it is OK to remove the GAL from the
programmer's socket.
The steps in programming a GAL:
1. With a text editor create the source file and save this
file as "name.pld" (add the extension .pld!)
2. Assemble the source file. As a result of this you'll get
a JEDEC file ("name.jed").
3. Select the GAL type
4. Insert the GAL in the programmer's socket
5. Perform the <a href="menempty.html">Blank test</a> to verify that the GAL is empty.
When the GAL is not empty, then you must first erase the GAL
before it can be programmed, use therefore the function <a href="menerase.html">Erase</a>.
6. Initiate programming by selecting <a href="menprog.html">Program</a>.
7. Take the GAL out of the programmer's socket, - DONE !
