CPLD Upgrade and new Toolchain
Since we introduced our new banking logic to access 512k RAM, our glue logic is being accommodated by a Xilinx XC9572 (without XL) CPLD. This component has long been deprecated when we started using it, because it was what we had available. The upgrade path would be the successor family XC95..XL. Those have been rather expensive lately, and finally AMD/Xilinx has axed it’s whole CPLD line in 2024, leaving us at a dead end. Where do we go from here?
