SignatureIP Achieves PCI-SIG® PCIe® 5.0 Certification, Joining Elite Group on Official Integrators List

Next-Generation NoC Pioneer Demonstrates Industry-Leading PCIe Controller IP and Scalable IO Subsystems on Siemens Veloce proFPGA CS Platform

MILPITAS, CA, UNITED STATES, September 4, 2025 /EINPresswire.com/ -- SignatureIP, the pioneer of next-generation Network-on-Chip (NoC) and Interface subsystem solutions, just announced that its PCIe Controller IP has successfully passed PCI-SIG^® compliance testing and has been added to the official PCI Express^® 5.0 Integrators List.

Additionally, running the IP on Siemens’ industry-leading Veloce™ proFPGA CS hardware, verifies the scalability and flexibility of SignatureIP's complete IO Subsystem solutions.

Purna Mohanty, CEO of SigntureIP, said that "Achieving PCI-SIG certification for PCIe 5.0 represents a significant validation not just of our engineering excellence but also our commitment to delivering cutting-edge connectivity solutions. SignatureIP PCIe 6.2 Controller incorporates the the performance features configurable based on the system requirement, and is architected for deployment in a broad spectrum of applications in ASIC and FPGA. By using Siemens’ Veloce proFPGA CS, we've demonstrated not just PCIe compliance but also the full capabilities of our connectivity IPs in scaling IO Subsystems. This approach accelerates our customers' path to silicon success.”

Siemens’ Veloce proFPGA CS enabled SignatureIP to demonstrate:

- PCIe 6.2 Compliance with backward compatibility: Full specification compliance
- NoC Scalability: Real-world demonstration of Network-on-Chip performance
- IO Subsystem Integration: Demonstrating comprehensive IO connectivity solutions with scalable architecture with SignatureIP System-level IPs that includes System-level Cache, IOMMU, Proxy Cache Designs.

"It is exciting to see IP providers like SignatureIP take full advantage of the unique capabilities of Veloce proFPGA CS to achieve PCIe 5.0 certification. It demonstrates the convergence of two critical technologies for next-generation computing. SignatureIP’s PCIe/CXL interface IP delivers the high-bandwidth, scalable connectivity that modern systems require for connecting CPUs, GPUs, and memory—the fundamental building blocks of an AI infrastructure. The advanced FPGA-based prototyping capabities of Veloce proFPGA CS allow joint customers to not only integrate the IP into their designs but also verify functionality in an at-speed prototyping environment. " said Juergen Jaegar, Director, Prototyping Product Strategy, Siemens Digital Industries Software.
