WebYou should really formally verify any FIFO you write. In this case, a short verification run shows this FIFO will fail as early as the third clock: First clock, rst is active. Second clock, rd_en is active. rd_pt doesn't move since the FIFO is empty. FIFO_cnt still moves forward. WebApr 24, 2015 · I need to create a FIFO buffer in VHDL. I need to use a 2 dimensional array to storage data like (number of data) (n-bit data). If I create a single "big" array that storage for example 1000 entrys. Every new data clock I storage one slot. And every output data clock I output a data. What happen if this two clocks occour near at the same time?

WebMost FIFO's (including this one to a brain-dead extent) use what we refer to as a circular buffer. In a FIFO it's just a chunk of RAM that holds the data, plus a read and write pointer. The pointers are used to keep track of which ram locations are being used. WebMar 25, 2016 · Figure3 – Quartus Area Report for VHDL code of Digital Delay Line with delay = 1200. You should notice that the memory bits used in the report are: (8 x 1200) – 8 = 9600-8 = 9592. In the RTL code of the digital delay implementation using RAM, line 52 adds an additional delay at the output register “ o_data “.
