Verification & Compliance testing of VLSIs for Set Top Box application
Rebaca has been involved in certification testing of VLSIs for Digital Set
Top box application and Digital TV application. The test code has been
developed in C and resides in the target. The test code access HAL for
accessing the device registers. The Host software calls the test functions
via test scripts. The target software executes the function and return
back the response to the Host over the Host – Target communication link.
The host software maintains test logs in log files. The modules verified
are as follows:
- Verification and Validation of different modules of a system-on-chip
like:
- Graphics, Demux, Decoder, 1284, Smart Card, BIU, USB, 1394, UART, I2C –
Master & Slave, SPI, Timer, IR, GPIO, Digital Front end, Section
Filtering block, SPARC etc.
- Verification and Validation of various personality modules for
proper bus interface and its timing issues. The personalities include -
PCI, SH4 Processor, Coldfire Processor, Motorola 68K Processor, etc.
- Verification and Validation of modules like - Bus Arbitrator, SDRAM
cycle, Personality Interleaving
- Compliance suite testing for various modules like - 1284, 1394, USB,
Smart card etc.

Verification of VLSIs for Media application
Rebaca has been involved in testing of VLSIs for Media
application. The VLSI is simulated on a FPGA. The test code and a layer of
low level APIs is developed in C for the targeted functional module of the
VLSI. This is then downloaded to the target. The tests are invoked through
function entry points accessible from the console port of the debugger and
the responses are also obtained through the same port. The modules
verified are as follows:
- Digital Video Interface module - a unified interface module to
connect DTV, TFT, CSTN
- JPEG decode engine
- NAND flash controller
