Gtwiz_userclk_rx_active_in

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 · The GTH pins (GTH reference clock and RX channel pins) do not need constraining as this has already been done in the transceiver wizard. The RX data clock and output are connected to the prototype …

WebThis issue occurs because the clock placer is not properly accounting for the clock routing restrictions around the PS8 blocks. It can be avoided by either assigning clock roots or floorplanning loads so that clock signals do not pass through PS8 blocks.

WebWhen I connect ILA with my frequency counter I dont see TXOUTCLK running (I see less than1Mhz). when I build GTH with 8B/10B encoding enable (with same setting), I see TXOUTCLK was around 206MHz. My application doesnt need 8B/10B encoding. With same design in xilinx simulation shows 40.5MHz generating (with raw data ). WebBut the data from RX looks totally crashed. Here are some of the points that I have confirmed: - Data path width is 16 bits, so userclk is ~250 MHz. userclk for both TX and RX are generated with correct frequency. gtwiz_userclk_tx_active and gtwiz_userclk_rx_active are both 1. - rxcommadeten, rxmcommaalignen, and … WebThe gtwiz_userclk_tx_active_in port is 1-bit wide even though I have four transmitters (each with their own TXUSRCLK and TXUSRCLK2 clocks).

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.

It can be avoided by either assigning clock roots or floorplanning loads so that clock signals do not pass through PS8 blocks. WebThe example design generated for this configuration instantiates four receiver user clocking network helper blocks in the example design, but only one transmit user clocking network helper block. Further, the core's gtwiz_userclk_rx_active_in port is four bits wide, and the gtwiz_userclk_tx_active_in port is one bit wide.
