Digital Vector Testing
Forwessun provides expert Digital Vector Testing for a variety of digital and mixed-signal ICs, ensuring reliable and comprehensive test coverage.
Digital Vector Testing at Forwessun
Forwessun has been designing and debugging digital vector tests since 2005, building an extensive and continually expanding library to support a wide variety of digital and mixed-signal integrated circuits (ICs). Our highly skilled team delivers accurate, reliable testing solutions for your digital devices, ensuring optimal performance, quality, and traceability across your production line.
What is Digital Vector Testing?
Digital vector testing is a method for verifying that each IC on a PCB operates correctly by applying sequences of digital signals and analysing the outputs. When combined with vectorless testing, it provides a comprehensive solution for verifying both functionality and correct component placement. Examples of chips and devices we test include:
- Glue Logic & Serial Glue Logic
- TTL – CAN converter
- TTL – LIN converter
- TTL – RS232 converter
- TTL – RS485 converter
- Serial Flash / EEPROM / RAM / (SPI / I2C / Single Wire)
- ADCs (SPI / I2C / Parallel Out)
- DACs (SPI / I2C / Parallel In)
- Real-Time Clocks (SPI / I2C)
- Temperature sensors (SPI / I2C)
- Voltage supervisors/watchdogs
- Parallel Flash (CFI etc.)
- Parallel RAM (DDR1, DDR2 etc.)
- Boundary scan / JTAG
Vectorless Testing and Presence/Orientation Verification
When testing the entire IC is impractical, vectorless testing (also known as Testjet, VTEP, Framescan, or Opens Express) is used to ensure that all pins, digital and analogue, are correctly soldered. This is often combined with a digital bus test — called a “Presence and Orientation” test — to verify the correct IC is fitted and the power pins are functional, reducing the risk of dry joints or misaligned components.
Benefits of Digital Vector Testing at Forwessun
- Accurate IC identification, orientation, and presence verification
- Early detection of faults and assembly issues
- Support for mixed-signal devices and complex bus protocols
- Reduced rework and increased production reliability
- Integration with ICT for streamlined, efficient testing
Bus Protocols Experience
We have in-depth experience working with a variety of BUS protocols:
- SPI: Read Register, Chip ID
- I2C: ACK Test
- UART: Read Register, Chip ID
- SWD: ACK Test, Read Register (when boundary scan is unavailable)
- MDIO: Read Register
Our team is continuously working hard to expand this list to stay ahead of industry needs and to provide comprehensive testing solutions. Explore our digital test software solutions.
