Abstract
The Purpose of this Master thesis is to integrate the Xilinx PCI-Express interface core to the
GRLIB framework. Xilinx Spartan6 Endpoint block for PCI-EXPRESS is generated using
Coregen and integrated with the GRLIB framework. The design accounts for crossing clock
domains as it is inevitable in a system of chip design with multiple components running at
different frequencies. The implementation satisfies the Specification provided by AMBA and
PCI-EXPRESS. The performance and area requirement are taken into consideration and
different forms of the design is implemented in order to address it. The communication
between PC and GRLIB memory environment and the other way around is performed and
verified. Simple C codes are developed in order to initiate transfers and also to verify the
design. Debugging tools like GRMON, LSPCI and drivers provided by Xilinx are used for
analysing and verifying the design. Using GRMON the PCI-EXPRESS debug environment
could transfer data at the rate of 120 Mbits/second from PC to the memory of GRLIB. The
complete design work was carried out at Aeroflex Gaisler AB.
