ICD provides a centralized, shared, Impedance Planning Environment that connects Materials, PDN Analysis, Stackup Planning, Signal Integrity, PCB Design and Fabrication consolidating the impedance control from schematic to fabrication. The impedance is planned pre-layout and flows through the design process to fabrication – achieving right first time design.
The Stackup Planner features a precision 2D Boundary Element Method (BEM) Field Solver providing Altium customers with the accuracy and simulation speed they need for high-speed PCB Design. Seamless integration with the Altium Layer Stack Manager, allows the transfer of substrate materials for the correct trace impedance and automatic creation of Design Rules for differential pairs and trace routing.
Impedance is the key factor that controls the stability of a design – it is the core issue of the signal integrity methodology. A properly planned PCB substrate can effectively reduce electromagnetic emissions, crosstalk and improve signal integrity providing a low inductance power distribution network. It can also improve the manufacturability of the product, reduce costs and increase product performance and reliability.
AC Power Distribution Network (PDN) analysis is often overlooked during the design process. Poor PDN design can result in unusual, intermittent, signal integrity issues. These include high crosstalk and excessive emission of electromagnetic radiation, degrading performance and reliability of the product.
The ICD PDN Planner allows the analysis of an unlimited number of power supply configurations simultaneously. A typical high speed, multilayer PCB has five or six individual power supplies that all serve a different purpose, and must be regulated to maintain power integrity during high current switching up to the maximum frequency. With a frequency range up to 100 GHz, the PDN Planner analyzes the AC impedance of each on-board PDN, including capacitor selection, and simulates plane resonance peaks giving a concise graphical view of the entire network.
