This page contains tidbits on writing FSM in verilog, difference between blocking and non blocking assignments in verilog, difference between wire and reg, metastability, cross frequency domain interfacing, all about resets, FIFO depth calculation,Typica
All of the preceding examples were coded with Verilog-2001 enhanced and concise ANSI- style module headers. In reality, to make the designs work with the Cadence Verilog simulators, I had to also code Verilog-1995 style module headers and select the appropriate header using macro definitions. ...
I referred some examples online, where they were able to shift from online to another. https://electrosofts.com/verilog/fsm.html Aug 23, 2018 #4 T ThisIsNotSam Advanced Member level 5 Joined Apr 6, 2016 Messages 2,665 Helped 398 Reputation 796 Reaction score 485 Trophy poin...

The examples in this section use VHDL attributes to define the required coding - the same ideas can be used in Verilog, but using meta-comments (special comments that are interpreted by the synthesis tool). Using Synopsys Synplify Pro® with FSMs ...
The coding examples are attached to this answer record. The answer record also contains information related to known issues and good coding practices. Note: Each coding example can be used to directly create a Vivado project. Please refer to the header in each source file for the Synthesis attr...

Chapter 1 contains an introduction to FSMs, the Mealy and Moore models of an FSM, differences between synchronous (clock-driven) FSMs and asynchronous (event-driven) FSMs, the state diagram and how it can be used to indicate sequential behaviour and the inputs and outputs of a system. This ...
