I have to design a 32-bit ALU by aggregating 8 4-bit ALU\'s I\'ve already designed. What I can\'t figure out is how to take the 8 4-bit signals and link them to the 32-bit signals for the 32-bit ALU.
I am a beginner in SystemC programming and there is one thing I noticed (look开发者_开发知识库ing in the SystemC official documentation): all types that I used to deal with in VHDL simulations have no
I\'m in the process of learning VHDL and I\'m trying just learning from examples, syntax guides, and experiments.
VHDL allows the following substitutions, presumably because some computers might not s开发者_Python百科upport the vertical bar (or pipe symbol) (|) or the hash (or pound sign / number sign) (#):
It is easy to update a combinatorial process and forget to update the sensitivity list. In Verilog the @(*) was introduced to say the sensit开发者_运维问答ivity list is what is used in this process. I
I want to \"create\" a type \"my_type\", which is a开发者_如何学Python std_logic_vector(...), like this C/VHDL fake code:

This question asks the general question. I\'m asking about VHDL in particular, since the tools 开发者_运维知识库that question\'s answer mentions are for Java and PL/SQL. It doesn\'t need to be perfect
Say I need a signal to represent numbers from 0 to 5; obviously this needs 3 bits of std_logic to be represented (i.e if MAXVAL=5, then bitwidth= {wcalc \"floor(logtwo($MAXVAL))+1\"}).
I\'ve created a testbench 开发者_高级运维to test an adder carry circuit (although it doesn\'t matter what the circuit is doing)
