Patch created on October 01 2018 Patch Case#: 595322 //**************************************************************** Description: For cr3 rsfec topology rules, channel restrictions for ELANE PTP settings were incorrect when odd rsfecs were disabled. The odd rsfecs are rsfec_1 and rsfec_4. These rsfecs correspond to the PTP_PLL channels and thus should not restrict ELANE settings. Without removing these restrictions this will cause a fitter error since correct IP settings are not legal according to the RBC. There was also another issue with the RBCs for ehip_3 in ELANE_4CH_PTP_FEC configuration. The incorrect channels were being constrained and the RBC contradicted itself - causing another fitter error. This patch fixes the issue. Caution - You must either have previously installed the Quartus Prime 18.1 software or must install the Quartus Prime 18.1 software before installing this patch. Otherwise, the patch will not be installed correctly and the Quartus Prime software will not run properly.
