17 years agoHi Jake,
Since i want to add some video block to your reference design i am thinking of modifying the eth_test_top.v. One thing i do not understand is that why the clk_sopc needs to be generated by top_pll. top_pll top_pll_inst( .inclk0 (clk_100mhz[0] ), .c0 (clk_sopc ), .c2 (sram_clk ) ); clk_sopc and the clk_100mhz[0] have the same clock frequency and there is no clock phase shift. But if i do use clk_100mhz[0] as the input to the sopc system the ethernet does not work... another thing is, as i understand the reset_n_sopc in the reset module is only needed for PHY reset. So for video block example i can simply use reset_n, right? reset# (.CLKS_PER_SEC(100000000), .RESET_PER_NS(1000000)) reset_sopc_inst( .clk (clk_sopc ), .reset_req (~reset_n ), .reset_n (reset_n_sopc ) );
