Implementation Status
Schematics were completed in 2007, and layout was finished in March 2008. The first prototype boards were fabricated and have been assembled as of mid-April 2008. The first of the prototypes was powered-up April 25 2008 at meerKAT. During May tests have been done that have verified basic functionality of the Virtex 5 FPGA, the Actel management FPGA, the XAUI/10GbE connections, the DDR2 memory for the FPGA, the QDR memory, and the ZDOK connections. The PowerPC and associated devices have also been tested. These tests have revealed several issues whose solutions have been incorporated into a new board revision; this revision was completed in July 2008. Assembled boards were received on 6 August 2008 and testing was completed in November 2008.
A (tentative) first production version has been designed and is currently being manufactured and assembled.
