By using MPCS, the user does not need to specify the location of SD_EXT_x_REFCLKn using a constraint file. Example snippet of the implementation: DIFFCLKIO DIFFCLKIO_inst ( .CLKIN0_P (sd_ext_0_p_i), .CLKIN0_N (sd_ext_0_n_i), .CLKIN1_P (), .CLKIN1_N ...
Solution: The MPCS IP has an update that added the FVCO checker. It is available on Radiant 2023.2 or later. In case the user cannot upgrade to the said version, kindly file techsupport ticket to have an appropriate software patch. ...
Description: From FPGA-TN-02245-1-1-CertusPro-NX-SerDes-PCS-User-Guide of the Appendix C. Calculating Parameters for SerDes PLL, it shows the available data rates with respect to the reference clock. However in any case that the desired data rate for ...
Solution: The only requirement is to power-up the channel 1 of the used quad even if this channel is unused. The rest of the unused channel/s can be left floating or not connected. Refer to Section 13.5 of the CertusPro-NX SerDes/PCS User Guide ...
Description: An iteration limit error may appear when simulating using the PCS IP core. Solution: There are several possible causes for the Iteration Limit Errors. The polarities of the PCS resets are incorrect. When the SERDES Quad reset is removed, ...
