Exar Triples Verification Productivity Using Synopsys' VCS Solution With SystemVerilog Testbench Automation

Exar Develops and Deploys Advanced SystemVerilog Verification Environment and Reference Model with VCS® Native Testbench Technology

PRNewswire-FirstCall
MOUNTAIN VIEW, Calif.

Synopsys, Inc. (NASDAQ: SNPS), a world leader in semiconductor design software, today announced that Exar Corporation (NASDAQ: EXAR), a leading provider of high- performance, mixed-signal silicon solutions for the worldwide communications infrastructure, has adopted Synopsys' VCS® comprehensive RTL verification solution, a key component of the Discovery™ Verification Platform, to speed chip development and increase verification quality. Exar has taken advantage of the VCS solution's SystemVerilog testbench automation capabilities to rapidly develop an advanced, extensible verification environment based on open standards, leveraging the latest coverage-driven, constrained-random methodologies. Exar used these methodologies with the VCS solution to identify bugs early in the design process where they were easily corrected.

"After evaluating other tools, we chose the VCS solution because of its leading support for verification with SystemVerilog and the high performance of its Native Testbench technology," said Sameer Goyal, principal engineer at Exar. "With the VCS solution, we developed a sophisticated coverage-driven, constrained-random verification environment using SystemVerilog with just four months of effort. This helped us shorten the development cycle down to one third compared with previous projects."

Exar engineers developed a sophisticated SystemVerilog verification environment, using the VCS solution to simulate a complex design, generate randomized stimulus and measure functional coverage. The Exar team was able to quickly learn the SystemVerilog language and create an advanced testbench, which enabled full randomization of many aspects of the environment, from port configuration and the number of ports in the design, to characteristics of the packet and its sub-fields. They also developed a high-level reference model for checking correct design behavior, taking advantage of the VCS solution's support of advanced SystemVerilog language features, including object-oriented programming, classes, functional coverage, arrays, mailboxes and semaphores. Exar was able to quickly find unanticipated corner-case bugs in both the design and reference model by using the VCS solution's powerful constrained- random stimulus generation to create thousands of realistic tests.

"The VCS solution's support for SystemVerilog verification features enables customers like Exar to quickly build and deploy advanced testbenches based on open standards," said Manoj Gandhi, senior vice president and general manager, Verification Group at Synopsys, Inc. "VCS single-compiler technology for design, testbench, assertions and coverage provides higher performance, enabling our customers to verify designs in less time and with higher confidence."
