SMART’s PCB design flow has taken a major step forward now that Cadence’s Sigrity analysis engines are embedded into the Allegro design environment. PCB designers, electrical engineers and SI experts can now edit and analyze designs in parallel , freeing the design team to rapidly move through multiple design phases and avoid separate out-of-sync design files. The Sigrity analysis engines provide accurate results that correlate to lab measurements and provide seamless access to the Allegro layout tools, reducing the amount of time required for each PCB design.
