Verilog Synthesizable For Loop Example CodeThe two always blocks below perform the same purpose, except one uses a for loop and the other does not. Again, all the loop does is to expand replicated logic.1 2 3 4
using locally-declared loop counters. > In that sense the i variable is likened to a generate loop. In the sense that it is unrolled for synthesis, yes. But that is NOT the Verilog language semantics of a for-loop. Interestingly, you seem to be contradicting yourself here. I agree that...
We aim to be compatible with a wide range of EDA tools. For this reason, we strive to use as simple language constructs as possible, especially for our synthesizable modules. We encourage contributions that further simplify our code to make it compatible with even more EDA tools. We also wel...
SystemVerilog always_comb, always_ff. New and Improved. Verilog reg, Verilog wire, SystemVerilog logic. What's the difference? Verilog twins: case, casez, casex. Which Should I Use? SystemVerilog Arrays, Flexible and Synthesizable SystemVerilog Struct and Union - for Designers too...
Verilog generate statement is a powerful construct for writing configurable, synthesizable RTL. It can be used to create multiple instantiations of modules and code, or conditionally instantiate blocks of code. However, many Verilog programmers often have questions about how to use Verilog generate effe...

So it only does the first loop. I guess this is a known bit of missing functionality? I guess there might be issues in how the constant number of loops is lowered to SV? I think it needs to end up obviously still constant so it is synthesizable....

Note: Explicit delays are not synthesizable into logic gates ! Hence real Verilog design code always require a sensitivity list. Sequential Element Design Example The code shown below defines a module called tff that accepts a data input, clock and active-low reset. The output gets inverted whene...
Synthesizable code Logic synthesis tools cannot accept all Verilog code. The designer needs to ensure that the hardware description language code is a cycle-to-cycle register transfer level description. Loop structures such as while must provide termination conditions in the form of signal edges (such...
