e-book digs deep into I2C testing
A new eBook explains how the circuit board design validation process can be accelerated by performing at-speed functional tests on the Inter-Integrated Circuit (I2C) bus interfaces on prototype boards before their operating software is available. The test strategy involves temporarily inserting embedded instrumentation intellectual property into an on-board field programmable gate array (FPGA) and applying boundary-scan or JTAG tests to verify structural integrity.
Published by ASSET InterTech the eBook describes several methodologies whereby the I2C interfaces on non-booting prototypes or fully assembled boards can be tested and validated. In the case of prototype boards, the design team would not have to wait for operating firmware before validating the functionality of I2C. In other words, functional hardware verification is decoupled from functional software development.
In addition, the time spent on developing traditional functional tests is avoided as well. On assembled boards that fail to boot, these same methods could eliminate faults in the board’s I2C interfaces as a root cause of the failure.
“Developing and performing a functional test suite for a new circuit board design can be a very laborious and time consuming task,” said Kent Zetterberg, an ASSET product manager and author of the new eBook. “A test strategy based on embedded instruments not only saves time and money, but it also provides a lot more diagnostic information on the root causes of faults and failures than a traditional functional test ever could.”
