XC3000L CLB Switching Characteristics Guidelines
Testing of the switching parameters is modeled after testing methods specified by MIL-M-38510/605. All devices are 100%
functionally tested. Since many internal timing parameters cannot be measured directly, they are derived from benchmark
timing patterns. The following guidelines reflect worst-case values over the recommended operating conditions. For more
detailed, more precise, and more up-to-date timing information, use the values provided by the timing calculator and used
in the simulator.
Notes: 1. Timing is based on the XC3042L, for other devices see timing calculator.
2. The CLB K to Q output delay (TCKO, #8) of any CLB, plus the shortest possible interconnect delay, is always longer than the
Data In hold time requirement (TCKDI, #5) of any CLB on the same die.
