Very helpful for those just taking first steps in VHDL and Verilog. In your synthesizable For-Loop VHDL example, will the synthesizing process result in the same amount of hardware resources to implement r_Shift_With_For and r_Shift_Regular approach? Or does any of these approaches have some...
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...

只有for-loop语句是可以综合的。 14、设计时序电路时,建议变量在always语句中赋值,而在该always语句外使用,使综合时能准确地匹配。建议不要使用局部变量。 15、不能在多个always块中对同一个变量赎值 16、函数 函数代表一个组合逻辑,所有内部定义的变量都是临时的,这些变量综合后为wire。 17、任务: 任务可能是组...
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...

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...
Doing so means that VPI cannot override the definitions of functions handled in this manner. On the other hand, this makes them synthesizable, and also allows for more aggressive constant propagation. The functions handled in this manner are:...
