Incorrect formula in CRC calculation Time of Cyclone V Device Handbook Volume 1 - Incorrect formula in CRC calculation Time of Cyclone V Device Handbook Volume 1 Description Issue 540455 : Chapter 7 SEU Mitigation for Cyclone® V, section Devices CRC Calculation Time For Entire Device, Cyclone V Device Handbook Volume 1: Device Interfaces and Integration version 2018.03.02 It says as follows: Minimum time (n) = 2^n * tMIN But this is incorrect. It should be as follows: Minimum time (n) = 2^n / Minimum divisor setting * tMIN For example, 9ms of tMIN in Cyclone V E A2 device is the minimum time for divisor setting of 2 or n=1. When calculating the minimum time for divisor setting of 4 or n=2, the formula is as follows: 2^2/2*9=4/2*9=2*9=18 (ms) Custom Fields values: ['novalue'] Troubleshooting FB: 540455; False ['novalue'] ['novalue'] novalue novalue ['Cyclone® V FPGAs and SoCs'] ['novalue'] ['novalue'] ['novalue']
