Gen2 PCI Express Switch *
GDA complete Switch for PCI Express™ Serial Link Interface
PCI Express Switch
A PCI Express switch provides fan-out capability and enables a series of connectors for add-in, high performance I/Os. PCIe switches allow limited north bridge resources to be distributed to multiple I/O end points and enable efficient use of available bandwidth
The GDA® PCI Express Switch solution is a complete full functional PCI Express switch consisting of the switch core and the switch port controllers and implements the entire switch functionality like packet routing, interrupt, configuration access, power management and error reporting functions.
Superior Architecture
The GDA PCI Express Switch IP uses non blocking architecture and provides very high bandwidth and low latency. The architecture is also optimized for lower power consumption, and silicon footprint.
The GDA PCI Express Switch IP offers maximum off-load through the hardware logic and a high degree of dynamic programmability. This solution provides highly scalable bandwidth through configurable link width, data path width and clock frequency. Most Thoroughly Verified and Interoperable Design
The GDA PCI Express Switch is an exhaustively verified solution and is fully tested against design specific and protocol compliance checklist. The comprehensive directed and random tests ensures a very high coverage. The IP is verified with leading PCIe verification IP’s and the verification environment can be configured to run with all the major simulators. The reusable block level verification environment and the formal verification methodology enhance the quality of verification process and add more confidence to the design verification.
The GDA PCI Express-Switch solution leverages years of experience in creating reusable IP for Ethernet, RapidIO and PCI Express technologies. The expertise in creating those system validated solutions with RTL, synthesis, simulation, board and software ensures delivery of lower risk, compliant and interoperable solution
Ease of Integration
The GDA PCI Express Switch design is fully synchronous and adheres to standard synthesis, test insertion and physical design practices. The solution allows licensees to easily migrate among COT, FPGA, Gate array, structured ASIC and Standard cell technologies. The IP with its flexible user logic interface can be easily integrated into a wide range of applications.
Superior Comprehensive Support
The GDA PCI Express Switch solution comes with a superior support model that offers round the clock telephone, email, web based support and free code updates during the support period. Support documents including a data sheet, verification guide, synthesis guide and application notes are also offered. To build a full-system solution the GDA partner eco-system provides access to additional components such as verification IP, PHYs and related design services.
