When I have one transistor with floating Body , the spectre will gives following warning:
"Notice from spectre during topology check.
Only one connection to node `I0.net9'.
Warning from spectre during heuristic topology check - set topcheck=fixall to fix all floating nodes.
WARNING (SPECTRE-7): No DC path from node `I0.net9' to ground."
My question is:
(1) how does spectre perform topology check?
(2) what is the definition for "DC path" and how does spectre identify these DC path?
If anyone can provide some description/documents, it would be great. Thank you.
