※ 引述《hunallen (一路上有你)》之銘言：
: 想請問一下
: 新的final roject.doc
: 第8頁
: 在輸出netlist時
: 第二行寫了const0
: 我們有需要說他是po嗎
The constant 0 is reported in the DFS list because it is used by:
[1] CONST0
[2] AIG 10 1
0
A constant will NOT appear in the DFS list if it is NOT the fanin of a gate.
A constant gate may directly fanout to a PO. For example:
aag 0 0 0 1 0
1
c
const gate directly fanouts to PO
In this case, you should have:
fraig> cirp -n
[0] PO 1 !0
fraig> cirg 1 -fanin 2
PO 1
!CONST 0
: 另外如果是const1
: 是輸出const1還是！const0呢
: 謝謝
I think the above case answer your question!
