fifo_counter is incremented ifwrite takes place and buffer is not full and will be decremented id read takesplace and buffer is not empty. If both read and write takes place, counter willremain the same. fifo_c

Verilog实验单端口RAM、简单双端口RAM、真双端口RAM、同步FIFO和异步FIFO模块。能够完全替代Xilinx官方IP核。软件版本:Vivado2018.3。 - mfkiwl/RAM_FIFO
我们实现的是read_cnt 和 write_cnt使用同一个时钟的情况,即synchronous FIFO; 关于async的实现,可以参考Advanced Digital Design With the Verilog HDL 2nd》chap9.7, async 考虑的则是跨时钟域通信的问题了。 代码如下: module fifo #( parameter WIDTH = 32, // data width is 32-bit parameter LOGDEPTH =...
This paper firstly introduces the Verilog HDL language and the characteristics of synchronous FIFOs and asynchronous FIFOs to solve the metastable problem as a starting point, using asynchronous FIFO design, which is one of the effective methods to solve the metastable state. This paper analyses ...
一个可以综合的Verilog 写的FIFO存储器 Synthesizable FIFO Model This example describes a synthesizable implementation of a FIFO. The FIFO depth and FIFO width in bits can be modified by simply changing the value of two parameters, `FWIDTH and `FDEPTH. For this example, the FIFO depth is 4 and...

21.Timing Analysis does not support the analysis of latches as synchronous elements for the currently selected device family 原因:用analyze_latches_as_synchronous_elements setting可以让Quaruts II来分析同步锁存,但目前的器件不支持这个特性 措施:无须理会。时序分析可能将锁存器分析成回路。但并不一定分析正...
