因为加入输入为4位信号,如果SUM_WIDTH要用clog2之后不加1的话,SUM_WIDTH的位宽为2bit,最大表达为11(3),而4位信号全为1时,sum应该为4,表达位宽不够。 这段code综合出来的电路是什么样的呢? 很明显,这样的电路可以达到设计的目的,但是并不是最优的,大家可以计算一下每个2bit full adder需要多少门,compara...

Quartus II使用了4個mux與4個comparator與4個mux,雖然已經沒有latch,但還是沒有使用q_o = 1'bx的結果好。 由此可知,使用multi if的寫法,真的造成synthesizer很大的負擔,在這麼簡單的程式中,就已經搞成這樣,很難想像在真的project中,那種複雜的程式結果會怎樣,所以不建議使用multi if寫法。

A CAS block is made up of an n-bit comparator, two n-bit multiplexers to select from inputs A and B where n-bit is the data width of A and B. There can be two configurations of the CAS block to sort the numbers in an ascending or descending order....
