Power integrity checking tool can run in Altium Designer

January 30, 2014 // By Graham Prophet
Electromagnetic simulation company Nimbic has become a partner in Altium’s Developer programme; the first outcome will be power integrity verification product - Altium PI-DC.

Nimbic writes electromagnetic simulation solutions for signal integrity, power integrity and EMI analysis; Altium PI-DC gives users the ability to validate DC voltage and current performance in their designs before prototype and production to avoid issues with power delivery, and to identify potential failure points. This includes high via currents that could cause fusing, or high resistance neck-down regions resulting in excessive voltage drop.

Built from the ground-up, Altium PI-DC is based on Nimbic’s specialised 3D full-wave electromagnetic solver, and is designed to address the requirements of large-scale power integrity problems; claims for it include fast solution times without compromise on accuracy.

Altium PI-DC integrates into Altium Designer as an optional extension, giving engineers a seamless environment for DC analysis. Nets for analysis are selected in Altium Designer with DC voltage drop and current density results displayed directly over the layout. This allows a designer to interactively identify and fix issues with no guess work about what layout structure might be causing the issue.

“BGAs have hundreds of power and ground pins with numerous supply rails requiring complex networks of capacitors to manage “pure” power. The sophistication of the PDN (power distribution network) requires engineers to be able to effectively analyse and make corrections early on in the design process,” said Daniel Fernsebner, Director of Technical Partnerships for Altium.

Altium PI-DC will be released before the end of March 2014 and will be shown at embedded world 2014 in Nuremberg, stand 4-206.
