Write Loops
Tools Supported: FastScan and FlexTest
Scope: Atpg, Fault, and Good modes
Usage
WRIte LOops filename [-Replace]
Description
Writes a list of all the current loops to a file.
The Write Loops command writes all feedback loops in the circuit to a file. For
each loop, the file contents show whether the loop was broken by duplication. The
file shows loops unbroken by duplication as being broken by a constant value,
which means the loop is either a coupling loop or has a single multiple-fanout
gate. The report also includes the pin pathname and gate type of each gate in each
loop.
