Question

Tim Edwards · Answer

Warnings are given by feedback entries which are like DRC errors except use a different but similar set of commands So feedback why feed why for short if you like and feedback find will track down those errors and tell you what they are

Tim Edwards · Answer

Extraction warnings are usually about labels and can be ignored FETs with source and drain tied together elicit warnings too which can be ignored

Weston Braun · Answer

I am getting warnings of the form ``` feedback find Feedback 1 device missing 1 terminal connecting remainder to node cascode bias 0 vss ``` Is this the type of message that is generated for dummy devices with source and drain tied together I dont have any unconnected devices and this seems to match the number of fully shorted dummy devices I have

Tim Edwards · Answer

Yes that s the behavior for source drain tied devices
