WebAll the statements inside the always block execute sequentially. Further, if the module contains more than one always block, then all the always blocks execute in parallel, i.e. always blocks are the concurrent blocks. Note Note that, we can write the complete design using sequential programming (similar to C, C++ and Python codes). WebWhen I use always_comb isim ends up in delta loop. I can step through with F8, but end the end of block jump to begin again without vistiting any other code. When I change it in always @ (*) there is no problem and simulation finish.

WebThe ‘always_comb’ block represents that the block should be implemented by using ‘combinational logic’; and there is no need to define the sensitivity list for this block, as it will be done by the software itself.
