In the world of modern electronics, complex FPGAs and microcontrollers often dominate the landscape. However, there remains a steadfast, educational, and practical niche for simpler programmable logic devices (PLDs). At the heart of this niche lies a legendary combination: the software environment and the Lattice GAL22V10 chip.
A standard .pld file for the GAL22V10 contains:
is the Windows-based Integrated Development Environment (IDE) for CUPL (Cornell University Programming Language). Originally developed by Logical Devices and later supported by Atmel (now Microchip), WinCUPL is abandonware but remains the standard free compiler for hobbyists. wincupl gal22v10

Looking for a specific WinCUPL example? Need a JEDEC file for a classic arcade GAL? Check the forums at JAMMArcade.net or the eevblog forum. The legacy lives on. In the world of modern electronics, complex FPGAs
is a pin-compatible, modern equivalent still widely used today. 2. Software Setup: WinCUPL
The GAL22V10 is not the fastest, densest, or cheapest programmable logic available. But it is the . It survives in 5V environments (unlike 3.3V CPLDs). It is in stock at major distributors. It requires no complex boot ROM, no configuration bitstream, and zero external components. A standard
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.
