However, the Vectrex circuit board didn't require a high level of performance. I then placed a 6-pin JTAG connector on the RLD to configure the CPLD. Finally, I created a custom mating connector for ...

The purpose of the prototype was to design and implement simple asynchronous transmitter and receiver logics with TTL-RS232 serial communication. The transmitter and receiver were designed as state ...

This paper studies on the elimination of the competitive and narrow pulse interference and on the reliability of the reset circuit in CPLD design. Methods of additional trigger, delay superposition, ...

Cons: Requires a larger CPLD with higher density and I/O pin count. Complex CPLD increases solution cost. Routing low-voltage analog telemetry to a single location increases circuit board congestion.

Thus, the first method is the most practical, and we'll show how we at Retro Devices Technology did it using a Xilinx XC9536XL CPLD – specifically targeted for 5V transistor-to-transistor logic (TTL ...

The reliability problems of the circuits in CPLD design are solved effectively. Published in: 2003 5th International Conference on ASIC Proceedings Article #: Date of Conference: 21-24 October 2003 ...
