WebJun 7, 2024 · CPLDs are useful for very simple logic, and more importantly to simplify board layout. You can put a CPLD and essentially do the complex routing on the inside. CPLDs generally have lower propagation delays, which also makes them attractive. There are not many uses for hobbyists. WebAllow a vacant row or two so there will be room for the decoupling caps. This also makes it easier to connect to the CPLD signal pins. Anchor the sockets with a bit of solder or epoxy depending on the type of perf board you use. Allow some extra room at the top (above pin 1 of the CPLD socket) for the JTAG connector and the power connector.

Webmanner. Both the DONE and INIT pins go Low, followed by the INIT pin going High indicating the start of configuration is requested. The state machine in the CPLD recognizes this event and begins to set up the SPI memory for a read operation. The operation begins by bringing spi_sn Low, followed by passing CCLK through to spi_c and
