CPU achieves silicon success with Customsim

Synopsys has announced that Loongson Technology achieved first-pass silicon success on its 65nm, multicore, high-performance Loongson-3 CPU design using Synopsys' Customsim circuit simulator.

The Customsim solution was deployed for timing and dynamic power simulation of advanced full-custom blocks, PLL, Hypertransport, register file and content-addressable memory (CAM).

The solution's Spice-level precision enabled Loongson to achieve first-pass silicon success with three times faster verification turnaround time.

Customsim unifies the simulation technologies of Nanosim, HSIM and XA with added multicore processing capabilities.

For full-chip verification, the Customsim solution is coupled to the VCS functional verification solution via a Direct Kernel Integration and is also combined with a unified analogue/mixed-signal (AMS) verification environment, which simplifies usability through a common set of inputs, outputs and device models.
