Cannot get clock clk_mac_ref
WebRMII. RMII uses a single centralized system-synchronous 50 MHz clock source (REF_CLK) for both transmit and receive paths across all ports.This simplifies system clocking and lowers pin counts in high port density systems, because your design can use a single board oscillator as opposed to per port TX_CLK/RX_CLK source synchronous clock pairs.. … WebApr 5, 2024 · The clock requesting code is quite repetitive. Fix this by requesting the clocks in a loop. Also use devm_clk_get_optional instead of devm_clk_get, since the old code …

WebSep 2, 2010 · Hello All, I have a Cyclone III with a large number of source-synchronous inputs and outputs that need to be constrained in the SDC file. I have tried to constrain then using the -reference_pin option as follows: # main OSC create_clock -period 10.000 -name CLK_100MHZ [get_ports {CLK_100MHZ}] ... WebInput. 1. In design example, the iopll_mac_clk instance uses this signal to generate the 395.833333MHz MAC clock that drives the mac_clkin input port of F-tile Interlaken Intel FPGA IP. The mac_clk_pll_ref frequency is 156.25MHz for default design example. You can update to match the iopll_mac_clk settings.

In verilog, when you are instantiating a module, that means you are adding extra hardware to the board. This hardware must be added before simulation starts (i.e. at compile time). Here, you can not add/remove hardware at each clock pulse. Once instantiated, the module is executed/checked for each timestamp of simulation, till the end.
