30/05/06 T. Alt – KIP HeidelbergHLT-PRR : H-RORC Verification The following tests have been successfully performed : - JTAG - PCI-33/32, PCI-33/64, PCI-66/32, PCI-66/64 - CMC-Connectors with DIU/SIU cards - Xilinx Platform PROM for configuration - Configuration with Flash & CPLD - DDR-SDRAM - TagNET The H-RORC passed CERNs Production Readiness Review in October 2005.

30/05/06 T. Alt – KIP HeidelbergHLT-PRR : H-RORC PCI DMA Write Performance Measured performance of DMA data cycles on the PCI bus. Theoretical bandwidth of a 64bit/66MHz PCI bus: 528 MByte/s For each DMA block length 10/100/1000/10000 transactions have been performed. The time for each transaction was measured by a counter with a 15ns granularity. The transmitted data was checked for errors: No errors occurred max. 2xDIU data rate

30/05/06 T. Alt – KIP HeidelbergHLT-PRR : H-RORC Summary & Sources The H-RORC is currently in production. A preproduction batch of 15 boards was received and is currently under testing. Schematics, Assembly and Bill of Materials can be found here H-RORC PRR related changes : 2 panel leds JTAG chain connected to PCI large capacitors removed from the backside to achieve PCI compliance power consumption needs to be observed for each design but was no problem up to now documentation is on the web
