CIRCAD

A powerful, yet easy-to-use PCB design package, CIRCAD includes all of the tools for circuit design and manufacturing that modern electronics engineers require. CIRCAD includes schematic capture, netlist generation, PCB layout, copper pour, design rule checking, several manufacturing output formats, and standard component libraries.

Key Features:

Easily accomplish more complex circuits with one set of signal names common to all schematic sheets
Multi-sheet schematics produce multiple net lists merged by the PCB editor
Manual routing or autorouting
Floods restricted areas and has individual clearance parameters for each different element type
DRC function enables engineers to verify correctness of circuit interconnections and ensure adequate clearances between various elements
