3. Schematic Capture and Simulation (System Capture & PSpice) System Capture

While both share the same underlying engine, they target different user tiers: Cadence OrCAD and Allegro 22.1 is Now Available

Before finalizing, the engineer uses the 3D Canvas (new in 22.1) to check mechanical collisions with the enclosure. The Rigid-Flex bending tool verifies the flex cable fold radius.

In version 22.1, Cadence merged the look and feel of OrCAD and Allegro. The main difference is and license tier .

For wearables and medical devices, version 22.1 dramatically simplifies rigid-flex.
