Qrouter Detail Routing Tool Version 1.2 Command Reference

resolution


Change the resolution of the values written to the output DEF file.

Usage:

resolution value

Summary:

The format of the DEF file that qrouter writes declares units in centimicrons. By default, qrouter will write all values in integer centimicrons. For any technology for which the resolution is finer than a centimicron grid, the resolution command allows a finer granularity. The value value provided is a scale factor compared against a unit centimicron. Thus, resolution 2 will result in output values that are rounded to the nearest half-centimicron (5 nanometers), and resolution 10 will result in output values that are rounded to the nearest nanometer.

Implementation Notes:

resolution is implemented as a built-in command in the Tcl version of qrouter.
