Soft Error Mitigation Controller v1.1 - Virtex-6 -1L Speed Grade ICAP Frequency Limited to 60 MHz
Description
The CORE Generator customization GUI allows the selection of up to 70 MHz for the ICAP clock frequency when targeting a Virtex-6 -1L speed grade. However, the Virtex-6 -1L speed grade only supports a maximum ICAP clock frequency of 60 MHz.
Solution
Users should select a frequency of 60 MHz or lower when targeting the Virtex-6 FPGA -1L speed grade. All other speed grades (-1, -2, and -3) support up to 100 MHz for the maximum ICAP frequency. This will be fixed in the v1.2 release of the core.
