SAN FRANCISCO Sigrity Inc. Tuesday (May 31) introduced two standalone tools customized for analysis of voltage drop, or IR drop, on packages and printed circuit boards (PCBs).
According to Sigrity (Santa Clara, Calif.), the tools, PowerDC PKG and PowerDC PCB, are the industry's first standalone tools optimized for IR drop analysis in packages and boards. The tools help designers budget end-to-end voltage margins for every device on the package and board to ensure designs are operational, the company said.
Jiayuan Fang, president and CEO of Sigrity, said that while IR drop has emerged more as an IC design issue, lower voltages due to shrinking linewidths have pushed IR drop concern to the area of package and PCB design. Fang said Sigrity saw that many of its users in large semiconductor companies were doing IR drop analysis on packages and boards with tools intended for other uses.
"We realized through contact with our users that there was a need for efficient tools intended specifically for system level analysis for IR drop, and that no such tool existed in the marketplace," Fang said.
Both version of PowerDC are designed to complement Sigrity's power integrity analysis tools by providing efficient, accurate direct current (DC) analysis of IC packages and boards to show voltage drops at various component locations, according to Sigrity. The Power DC products also find "hot spots" that potentially could cause problems and identify situations that could adversely impact electrical and thermal performance in the routing, the company said.
Sigrity said that both PowerDC PKG and PowerDC PCB would be available in June, each priced from $25,000.
