WebTo get deterministic latency in the received data the GTY is configured with the receiver buffer disabled. The application ARM startup code repeatedly resets the GTY until it comes up with the receiver at the correct phase to produce valid received data. This part works fine. My first attempt at loopback had the GTY transmitter buffer enabled. WebI am trying to make GTY IP with per lane configuration. We found cross clock domain problem between rx_clk [0] and rx_clk [3:1] to be fixed. How can I configure per lane reset structure ?

WebHowever, the wizard generates a transceiver module with a bunch of Rx ports that I'll never use since I'm only using the Tx (one way transmission). I looked through the options in the wizard and couldn't find a way to disable Rx (and not to generate the Rx-related ports). The ports that I do not wish to use are: gtwiz_userclk_rx_active_in, WebDec 15, 2024 · User RX clock - this is the clock that is used to clock out data to the user logic in the FPGA fabric. The frequency of this clock is also defined by the attribute ‘Free-running and DRP clock frequency’ on the ‘Physical resources’ tab of the GTH wizard.

It can be avoided by either assigning clock roots or floorplanning loads so that clock signals do not pass through PS8 blocks. WebThe register i_in_meta_reg is part of a synchroniser chain, clocked by the following chain, which connects to gtwiz_reset_clk_freerun_in on gtwizard_ultrascale_0_inst: It seems plausible that the reset synchroniser may be constrained to CLOCK_REGION_X0Y0 as part of the gtwizard instantiation (though I can't find an explicit AREA constraint …

WebThe 150 MHz reference clock is not free-running; it is generated by an external clock chip, which is not active until it is programmed by other logic in my design. I wait until that clock signal is stable and the transceiver's gtpowergood_out is high before asserting and releasing gtwiz_reset_all_in.
