|This powerful layout design rules check program is compatible
with all IC processes. Design rule violations are graphically
highlighted in color. Design and technology contraints are user
configurable through the use of a proprietary Design Rule Compiler.
This checker employs a sophisticated corner-based algorithm that is
both fast and accurate. It is a hierarchical checker, checking only
the first instance of a repeated cell within a design hierarchy,
allowing tremendous speed realtive to conventional "flat"
DRC programs. It is also incremental, checking only new or altered
cells within the specified area.
Leo 45 checks the geometry of a mask layout for design rule
violations. It identifies problems such as minimum-spacing
viloations, minimum-width violations, parallel edge-spacing
violations, and malformed-circuit constructions. It labels the
violations that it finds in the physical layout file (".phl")
that it checked, allowing you to correct the violations in context.
Leo45 checks geometries that use 45 and 90 degree angles.
