The SVX III Detector Emulator Module is a test-stand-only device implemented as a VIPA 9U Transition Module. Its purpose is to provide a single FIB module with data which follows the protocol defined for the SVX III ASIC. Under control of data values written to it by the FIB the SVX III Detector Emulator Module provides variable amounts of data in either fixed or pseudo-random patterns. Certain error conditions may also be created on demand in order to test system software response.
As a secondary feature the Detector Emulator Module provides partial emulation of a second Port Card such that diagnostic software may determine what DDR commands were actually sent by the FIB during a readout sequence.
The SVX III Detector Emulator Module fits into the system only during system startup and integration. It is not meant for use in the delivered system and is inappropriate for use outside the engineering development area. No user-level software is provided for the device. The SVX III Detector Emulator Module is not guaranteed to provide timing identical to that of the SVX III chip/Port Card combination. The Detector Emulator Module is only useful for checking the response of the system to data conditions and for engineering analysis of setup and hold times within modules.
For operation the SVX III Detector Emulator Module requires a FIB module and a VIPA subrack. Power for the module is provided by the subrack, and necessary control information is provided by the FIB. The VIPA subrack must be outfitted with a J3 backplane for command and data connection.
