Cadence synthesis

[jishnuv3396]

I need to synthesize the inverter chain having 10-not gates and find its delay ,While using cadence synthesis the tool optimize the chain to a single wire,is any option to do don't_touch the chain,please help me

You do not need to synthesize a circuit that was put together by hand. Your premise is wrong.

There's a synthesis keep attribute to keep combinational nodes, review the tool reference.
