WebI have a question about importing an IP core from Designware (Synplify Premier) to Vivado project via EDF netlist. I created an instance of DW_fifo_s2_sf in Synplify and synthesized it. Now I got my EDF netlist which I want to import in Xilinx Vivado project (so there is no encrypted IP core!). I instantiated the EDF netlist in Vivado to run ...

Corner Cases to Verify Synchronous FIFO

WebJul 2, 2024 · AE and AF flags can be designed into the FIFO chip or ASIC/PLD IP, otherwise extra logic circuitry can be added around the FIFO to do it. For bursts: if the FIFO write data or read data is to be moved by burst transfer of blocks, such as across a bus in data packets, then the AE/AF thresholds can be set for when there is sufficient write space ... WebJan 28, 2024 · 2. I'm trying to figure out the corner cases for verifying a synchronous FIFO during hardware verification. My setup is a very simple two ports synchronous FIFO (write/read) and the write clk frequency is same as read clk frequency.

WebAug 5, 2024 · I think asynchronous FIFO actually internally uses gray code counter to pass the write/read address pointer across the two clock domains. You will have metastability issue if more than 1 bit is toggled in one clock domain, but no all the bits are captured by the other clock domain. One 1 bit can toggle in a gray code counter and the value stays ... WebApr 1, 2011 · If you choose to code your own dual clock FIFO, you must also create appropriate timing constraints in Synopsis Design Constraints format (.sdc).Typically, you set the read and write clock domains asynchronous to each other by using the set_clock_groups SDC command.
