PCI IP Core PCI-T32 32-bit, 33 MHz PCI Target Interface Core

The main PCI-T32 Interface core purpose is to isolate the user from having to solve complex problems of the PCI interface implementation and let the user instead focus on the application development.

The PCI-T32 Interface supports 32-bit address/data bus and operates up to 33 MHz (66 MHz optional) PCI clock frequency. It is fully compliant with the PCI Local Bus Specification, Revision 2.3.

The PCI-T32 Interface is a Target–only PCI Interface core. The interface implements 64 bytes of PCI Configuration Space registers. It is possible to extend the Configuration Space up to 256 bytes if required.

The Target supports up to six Base Address Registers with both I/O and Memory space decoding from 16 bytes up to 4 GB.

The Target supported commands are:

• Configuration Read, Configuration Write
• Memory Read, Memory Write, Memory Read Multiple (MRM), Memory Read Line (MRL), Memory Write and Invalidate (MWI)
• I/O Read, I/O Write

Support

The core as delivered is warranted against defects for ninety days from purchase. Thirty days of phone and email technical support are included, starting with the first interaction. Additional maintenance and support options are available.

Verification

The core has been verified through extensive simulation and rigorous code coverage measurements.

Deliverables

The core is available in ASIC (synthesizable HDL) and FPGA (netlist) forms, and includes everything required for successful implementation:

• HDL RTL source code (ASICs) or post-synthesis EDIF netlist (FPGAs)
• Sophisticated HDL Testbench
• Simulation script, vectors, expected results, and comparison utility
• Synthesis script (ASICs) or place and route script (FPGAs)
• Comprehensive user documentation, including detailed specifications and a system integration guide
