Power dis­tri­bu­tion anal­y­sis

DEMM Engineering & Manufacturing - - MAINTENANCE MATTERS -

Altium along with Aus­tralian based In-Cir­cuit De­sign has re­leased new ex­ten­sions for Altium De­signer for ad­vanced stackup plan­ning and power dis­tri­bu­tion net­work anal­y­sis.

With the in­creas­ing chal­lenges con­cern­ing high-speed sig­nals – not only be­cause of high clock fre­quen­cies, but also be­cause of faster edge rates – PCB de­sign­ers need to have anal­y­sis tools that al­low them to suc­cess­fully de­sign with fewer it­er­a­tions.

The two new ex­ten­sions for Altium De­signer, the ICD Stackup Plan­ner and ICD power dis­tri­bu­tion net­work (PDN) plan­ner, are ac­ces­si­ble from within the de­sign tool to pro­vide for seam­less anal­y­sis.

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 f lows through the de­sign process to fab­ri­ca­tion.

At­ten­tion to crit­i­cal place­ment, fanout, matched length and dif­fer­en­tial pair rout­ing are vi­tal for more and more main­stream de­signs. How­ever, plan­ning the mul­ti­layer PCB stackup con­fig­u­ra­tion is one of the most im­por­tant as­pects in achiev­ing the best pos­si­ble per­for­mance of a prod­uct. The ICD stackup plan­ner en­ables en­gi­neers and PCB de­sign­ers to master this chal­lenge.

With a fre­quency range up to 100 GHz, the ICD PDN Plan­ner an­a­lyzes the AC impedance of each on-board PDN giv­ing a con­cise graph­i­cal view of the en­tire net­work in­clud­ing plane res­o­nance peaks.
