Simultaneous, on-chip FPGA delay measurement is a powerful technique for characterizing the performance of FPGA designs. However, there are several pitfalls and tradeoffs that must be considered when using this technique.
One pitfall is the potential for measurement errors due to coupling between measurement signals and other signals on the FPGA. This coupling can lead to inaccurate measurements and must be carefully controlled through proper design techniques.
Another tradeoff is the tradeoff between measurement accuracy and measurement speed. More accurate measurements require longer measurement times, which can impact overall system performance. Therefore, it is important to carefully balance measurement accuracy and measurement speed to obtain the best overall system performance.
Additionally, the choice of measurement technique can also impact the accuracy and speed of on-chip FPGA delay measurement. For example, pulse width measurement techniques may be faster but less accurate than time interval measurement techniques.
Finally, the choice of measurement circuitry can also impact the accuracy and speed of on-chip FPGA delay measurement. Careful consideration must be given to the design of the measurement circuitry to ensure accurate and reliable measurements.
Overall, simultaneous, on-chip FPGA delay measurement is a powerful technique for characterizing FPGA designs, but careful consideration must be given to the potential pitfalls and tradeoffs to obtain accurate and reliable measurements.
