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}] ... WebThe ETH_CLK pad which provide a clock to the PHY and The ETH_REF_CLK pad or ETH_CLK125 pad to get reference clock from the PHY. Depending on the configuration of your design, you have to configure the device tree, then the ethernet driver controls the clock configuration via the below registers.

WebFeb 20, 2024 · Here is an overview of the steps what psu_init.c sets for SGMII: Make sure the lane calibration is done. Put GEM in reset L0-L2 Set the pll_ref_clk to be 125 Mhz (PLL_REF_SEL*) Ref clock selection (L0_L*_REF_CLK_SEL_OFFSET) Set lane protocol to SGMII (ICM CFG) Set TX and RX bus width to be 10 (TX/RX_PORT_BUS_WIDTH) WebTXD[1:0], and RX_ER. REF_CLK is sourced by the MAC or an external source. REF_CLK is an input to the DP83848 and may be sourced by the MAC or from an external source such as a clock distribution device. The REF_CLK frequency shall be 50 MHz ± 50 ppm with a duty cycle between 35% and 65% inclusive. The DP83848 uses REF_CLK as the …
WebApr 12, 2024 · 2. 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.
WebThe ways to disable the REF_CLK signal can be: Disable or power down the crystal oscillator (as the case b in the picture). Force the PHY device in reset status (as the case a in the picture). This could fail for some PHY device (i.e. it … campground longs scWeb# SPDX-License-Identifier: GPL-2.0 %YAML 1.2 --- $id: "http://devicetree.org/schemas/net/rockchip-dwmac.yaml#" $schema: "http://devicetree.org/meta-schemas/core.yaml ... campground loris scWebJun 23, 2015 · clock_gettime () not supported on Mac. #300.
