Patent number: 11762019Abstract: A method can be used to test an electronic circuit. The method includes applying a test stimulus signal to the input node, collecting a sequence of N-bit digital test data at the output port. The N-bit digital test data is determined by the test stimulus signal applied to the input node. The method also includes applying N-bit to R-bit lossless compression to the N-bit digital test data to obtain R-bit compressed test data (R is less than N) and making the R-bit compressed test data available in parallel format over R output pins of the circuit.Type: GrantFiled: October 11, 2022Date of Patent: September 19, 2023Assignee: STMicroelectronics S.r.l.Inventor: David Vincenzoni

Publication number: 20230136596Abstract: A clock recovery circuit comprises an input node receiving a data signal having a data rate, and a digital oscillator producing a local clock signal with a frequency higher than the data rate. A counter clocked by the local clock signal has its count value sampled and reset at the rising and falling edges of the data signal, and a storage block coupled to the counter stores a count value that is updated in response to the current sampled count value of the counter lying in an update range between lower and upper bounds. A threshold value set is produced as a function of the updated count value stored in the storage block. Sampling circuitry receives and samples the data signal, and provides a sampled version of the data signal in response to the count value of the counter reaching any of the threshold values.Type: ApplicationFiled: October 17, 2022Publication date: May 4, 2023Inventor: David Vincenzoni
