PXI-based I2C Protocol Validation
Go beyond basic I2C compliance. Generate advanced reports in minutes!
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.
fSCL – SCL clock frequency
tLOW – LOW period of the SCL clock
tHIGH – HIGH period of the SCL clock
tHD;DAT – Data Hold time
tSU;DAT – Data Setup time
tHD;STA – Hold time for (Repeated) START condition
tSU;STA – Setup time for Repeated START condition
tSU;STO – Setup time for STOP condition
t_BUF – Bus Free time between START and STOP condition
tSP – pulse width of spikes that must be suppressed by the input filter
tRCL – SCL Rise Time
tFCL – SCL Fall Time
tRCL1 – SCL Rise Time after REPEATED START & after ACK bit
tRDA – SDA Rise Time
tFDA – SDA Fall Time
tVD;DAT – Data valid time
tVD;ACK – Data valid acknowledge time
VIL – LOW-level input voltage
VIH – HIGH-level input voltage
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.
