Logic 9 Synth Tutorial For Beginners

Logic Circuit Modeling

From what we have learnt in digital design, we know that there could be only two types of digital circuits. One is combinational circuits and the second is sequential circuits. There are very few rules that need to be followed to get good synthesis output and avoid surprises.

Combinational Circuit Modeling using assign

Combinational circuits modeling in Verilog can be done using assign and always blocks. Writing simple combinational circuits in Verilog using assign statements is very straightforward, like in the example below

assign y = (a&b) (c^d);

Combinational Circuit Modeling using always

While modeling using always statements, there is the chance of getting a latch after synthesis if care is not taken. (No one seems to like latches in design, though they are faster, and take lesser transistor. This is due to the fact that timing analysis tools always have problems with latches; glitch at enable pin of latch is another problem).

One simple way to eliminate the latch with always statement is to always drive 0 to the LHS variable in the beginning of always code as shown in the code below.

Sequential Circuit Modeling

Sequential logic circuits are modeled using edge sensitive elements in the sensitive list of always blocks. Sequential logic can be modeled only using always blocks. Normally we use nonblocking assignments for sequential circuits.

Verilog Coding Style

If you look at the code above, you will see that I have imposed a coding style that looks cool. Every company has got its own coding guidelines and tools like linters to check for this coding guidelines. Below is a small list of guidelines.

Use meaningful names for signals and variables
Don't mix level and edge sensitive elements in the same always block
Avoid mixing positive and negative edge-triggered flip-flops
Use parentheses to optimize logic structure
Use continuous assign statements for simple combo logic
Use nonblocking for sequential and blocking for combo logic
Don't mix blocking and nonblocking assignments in the same always block (even if Design compiler supports them!!).
Be careful with multiple assignments to the same variable
Define if-else or case statements explicitly
