  15. What is Pin-Locking? • Ability to retain device pin assignments for small to medium design changes • introducing a new variable to existing terms • adding input signals • inverting signals • introducing 1or 2 buried flip flops • adding p-terms • Requires a symmetric, uniform architecture • Requires software focus on pin-locking Technical seminar

  16. Pin-Locking is Key for ISP • Must retain pinouts as the design evolves • best done when the design software initially assigns pins • different from pinout pre-assigning • strong function of utilization in typical CPLD architectures • result of both architecture and software strategy • Pin-locking is valuable • eliminates or reduces PC Board rework • minimizes time to market, saves money • lowers designer frustration, risk Technical seminar
