IC Package Design Software

Flip-chip technology is commonly used for high I/O count designs. It greatly reduces inductance, allows high-speed signals, and possesses better heat conductivity properties.

An RDL (redistribution layer) is used to connect I/O pads to solder bumps. RDL congestion issues arise when a single layer in spite of manual routing is not enough to complete the routing for a sizable design due to sub-optimal I/O placement. Hence, in multiple die packaged systems for flip-chips, RDL routing is the key to packaging tradeoffs.

To achieve a high performance and low cost chip-package-board system, early feasibility analysis is a must to allow physical constraints to be coupled to electrical requirements. The physical constraints are used to minimize total wire-length of the RDL routes, whereas the electrical requirements are used to ensure accurate signal-power ratio, low power consumption, reduced inductance and lower thermal effects.

Designers can leverage a broad range interactive and automatic routing tools to reduce effort conducting fan-in/fan-out routing, automatic ball assignments on the package, and routing of the complete package.

Design Force supports integrations to best-in-class tools from partners such as ANSYS, AWR, Agilent and Synopsys for RF, Full Wave FD/TD, power integrity, and thermal extraction and analysis. Design Force also contains native EMI, signal and power integrity analysis for eliminating design errors.

Design Force includes an array of utilities and wizards to accurately define wire-bond profiles, bond pad placement, multi-die or bond-pad connections, managing the stacking of IC with online design and manufacturing rule checks.
