Adding New IC Patterns
- In the manufacturer handler's
initializePatterns():
registry.addPattern(ComponentType.OPAMP, "^NEWOPA[0-9].*");
registry.addPattern(ComponentType.OPAMP_MANUFACTURER, "^NEWOPA[0-9].*");
- Add to
getSupportedTypes():
types.add(ComponentType.OPAMP);
types.add(ComponentType.OPAMP_MANUFACTURER);
