Imagine you have a 16-bit CPU (like a 68000) and you need to generate a chip select for a RAM at address 0x1000 .
: Unlike older PAL chips, GAL devices are electrically erasable and can typically be reprogrammed up to 100 times. Output Logic Macro Cell (OLMC) wincupl gal22v10
CUPL syntax is a mix between C and Pascal. It is not a hardware description language (HDL) like Verilog; it is a netlist language with logic equations. Imagine you have a 16-bit CPU (like a
If you use a product term OE, it’s — can cause bus contention if not carefully timed. Global OE pin (pin 11) is synchronous to logic only if externally driven. wincupl gal22v10
