Cadence OrCAD 15.7: The Definitive Guide to a Legacy EDA Powerhouse

3. The "Yellow Screen of Death" (Graphics Glitch)

• Capture CIS – Robust schematic entry with component information system (CIS) for database-driven part selection.
• PCB Editor – A 16.0 precursor layout engine with solid constraint management, though less automated than modern versions.
• SPECTRA – Integrated autorouting (the legacy interface, pre-Allegro router unification).
• Layout Plus – Still available in this version, though being phased out.
• PSpice – Advanced mixed-signal simulation with decent model support for its time.

The Workarounds

15.7 was one of the last versions where the classic "OrCAD Layout" was still heavily used. Many designers hated the transition to PCB Editor because it had a steep learning curve and a different philosophy. This is exactly why 15.7 survived for so long in corporate environments—it let engineers stick to the classic workflow they knew and loved.
