Why does the F-tile Ethernet Multirate Intel® FPGA IP have hold time violations on its i_reconfig_clk domain?
Description
Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 22.2, the F-tile Ethernet Multirate Intel® FPGA IP can have hold time violations on its i_reconfig_clk domain.
These hold violations, as shown in the Synopsys Design Constraint (.sdc) timing reports, are typically seen with a “To Node” path containing “pld_avmm2_clk_rowclk.reg” and are similar to the following format:
eth_f_dr_top_wrapper_auto_tiles|z1577a_x0_y0_n0|avmm2_21~maib_ss_lib/x0/u23_2/pld_avmm2_clk_rowclk.reg
Resolution
To work around this problem, compile the design with multiple seeds until a passing seed is found.
This problem has been fixed starting in the version 22.3 release of the Intel® Quartus® Prime Pro Edition Software.
