Synopsys VCS HDL Simulator Supports AMD Opteron Processor on Linux

4/23/2003 - Synopsys, Inc. (Nasdaq: SNPS), the world leader in integrated circuit (IC) design software, announced that its industry-leading VCSTM HDL simulator will support the AMD OpteronTM processor-based Linux platforms for verification of system-on-chip (SoC) designs. VCS simulation on hardware platforms containing the AMD Opteron processor and running the 64-bit Linux operating system will provide engineers with the high performance and capacity needed to verify their next-generation IC designs. For the development of the AMD Opteron processor, AMD utilized VCS in an AMD AthlonTM processor-based Linux farm to achieve four billion simulation cycles per day and meet its functional verification milestones.

"AMD makes extensive use of VCS in Linux simulation server farms to meet stringent verification requirements and aggressive project milestones," said Rich Heye, vice president and general manager of AMD's Microprocessor Business Unit. "The combination of VCS and AMD Opteron-based Linux platforms can provide the high performance and scalable verification throughput needed for the next-generation of system-on-chip designs."

VCS provides the high performance and capacity required by design teams to verify today's multi-million-gate designs. The advances made available with 64-bit processor technologies such as the AMD Opteron processor further boost VCS performance and capacity. VCS takes advantage of AMD64 architecture to increase simulation capacity by allowing access to more workstation memory. Additionally, VCS' cross-compile technology will allow design teams to compile large designs on AMD Opteron processor-based Linux servers using 64-bit mode, and then simulate those designs using the compatible 32-bit mode. Using this flow, design teams take advantage of their 64-bit machines' capacity for the one-time, memory-intensive compile step while enabling them to utilize their existing 32-bit Verilog PLI-based software investments for simulation.

"Our customers typically use large simulation server farms consisting of VCS and advanced hardware platforms to meet their verification challenges," said Manoj Gandhi, senior vice president and general manager of the Verification Technology Group at Synopsys. "Extending VCS support of Linux platforms to include the AMD Opteron processor will allow mutual Synopsys and AMD customers to take advantage of the higher capacity and performance of this solution."

VCS support for the AMD Opteron processor-based Linux systems is scheduled for controlled availability in the second half of 2003. VCS is available immediately for a variety of computer platforms including DEC OSF1, Hewlett-Packard HP-UX, IBM AIX, Sun Solaris, and 32-bit Redhat Linux.
