Webhi everybody . I am trying to write my custom ip which contains a read packet fifo. my custom ip has an external clock and this clock should control the read fifo. so for testing version of my code I generate an example clock and I conencted it to rdfifo_top in my top module. but it doesnt work. with ipif_Bus2IP_Clk I can read my data from read fifo … WebI want to write into alter FIFO from state machine. I have registered data and wrreq signals. Now i am wondering, is it unsafe to set them both on the same clock cycle? Or should i …

WebNov 30, 2024 · The single-clock FIFO has a separate clock port clock, as shown in the diagram. The data in data[7..0] is written into the FIFO when the rising edge of Clock comes and wrreq is valid; when the rising edge of Clock arrives and wrreq is valid, the data in data[7..0] is written into the FIFO.

WebNov 20, 2015 · vGoodtimes said: With a loose definition of "state" you can ensure two process state machines have appropriately registered outputs. Eg, if "state" is defined to include the output bits, then the output bits will exactly match some of the state bits. I have seen this done, and I have seen it done very neatly in VHDL. WebFeb 27, 2012 · Pull the signal FIFO_WRREQ in the IDLE state and request data from the ROM address 00. The ROM is configured to output no registration mode, so the ROM data is transmitted directly to the FIFO write input and ignores the RESET signal. This reduces the data latency, because ROM_OUT is directly connected to FIFO_IN, and FIFO_IN is a …
