PXI-based I2C Parametric Validation Suite
Generate an I2C Validation Report in minutes for your chip!
I2C(Inter-Integrated Circuit) is a synchronous, 2-wire serial communication protocol. I2C Protocol is well suited for data transfer between ICs at relatively low speed. Its simple 2-wire interface simplifies IC design with fewer pins and smaller package thus reducing the board space and cost.
Soliton’s PXI based I2C Parametric Validation Suite tests for compliance based on the I2C specification defined by Philips Semiconductors (now NXP Semiconductors). The solution is open, modular and verifies spec compliance for Standard, Fast, Fast Mode Plus, and High-Speed I2C Modes with customization of the test possible at the TestStand or LabVIEW layer.
The Suite generates Timing, Syntax and Fault tolerance report of Philips I2C Spec Compliance for any I2C Slave Device within a matter of minutes.
Alternatively, customers can ship 3 DUT boards containing their desired slave device to Soliton Technologies and we will characterize the DUT and send the customer a comprehensive I2C Validation Report, within a cycle time of 1 week.

Test Plan Editor – LabVIEW based I2C Protocol Validation Tester allows users to create Test Scripts using a Script Editor tool by drag & drop of the Test steps in a sequence, and to configure the test parameters. The I2C Protocol Tester tool comes with all the Test Scripts that are needed for testing I2C compliance. If the device contains any special wakeup process or if the test has to extended beyond the I2C spec, the user can script the tests and execute the test.
I2C Waveform Viewer – During the test execution, user will be able to view the I2C digital waveforms that represents the I2C transactions between the master and the slave.
I2C Compliance report – The tool creates a compliance report for each test parameter at the end of script execution.
I2C Debugger – I2C Debug screen allows one to interactively peek and poke device registers.
