This year’s PCI-SIG Developers Conference took place at the Santa Clara Convention Center on June 5-6. Synopsys provided several demos covering the PCIe 5.0 Integrated IP Core, PHY, and Verification IP & source code Test Suites. There was a constant pool of inquisitive attendees interacting with our PCIe design and verification experts regarding the demos.

Debugging the complex serial protocols is the biggest challenge verification engineers face. It’s one of the most time and effort consuming activity affecting the schedule of every project. Traditional debug methodologies use a combination of loosely connected waveforms, log files, messages, and documentation, which are insufficient for productive debugging. Debugging SoC and block level issues using log files is tedious and time consuming. Design problems that appear in the later phases of the development cycle can be extremely difficult to track down and debug, thus putting project schedules at risk.

In today’s world of smartphones and tablets, high speed data at low power consumption is becoming increasingly important. MIPI M-PHY supports multiple applications with high data bandwidth and low power consumption which makes it a popular specification for mobile devices. Applications like JEDEC UFS 3.0 and MIPI UniPro 1.8 now support MIPI M-PHY 4.1 which provides high speed data at a rate of nearly 11Gbps (HS_G4). To learn more about latest UFS and UniPro specifications read our previous blog “High Speed Memory in Smart Phones: MIPI UniPro v1.8 for JEDEC UFS v3.0”. Data at such a high speed can lead to inter-symbol-interference (ISI). M-PHY provides a safety measure to prevent the loss of data at HS_G4. In this blog, we are going to talk about the ‘ADAPT’ feature and its advantages which were introduced in M-PHY 4.0.

Verifying today’s complex designs is time consuming, as simulations run for long time and millions of transaction are executed. Traditional approach of debug is to dump all the information of millions of packets in a log file, however it would always be challenging to filter out specific transactions from the huge log file. For example, in case of AXI Protocol, a fixed number of outstanding transactions are allowed during simulation, it would always be difficult to find out such outstanding transaction in the huge log file of a single run of simulation or during interactive simulation. It is one of the biggest pain point of debugging.

Synopsys VC VIP provides Verdi Protocol Analyzer, a protocol and memory aware debug environment . In my previous blog Debugging Memory Protocols with the Verdi Protocol Analyzer, I discussed the value add for using the Verdi Protocol Analyzer to debug memory protocols easily and efficiently. Also, I described how easy it is to look at a specific command as a transaction rather than as interpreted signals. In this blog I’m going to show another feature that makes Verdi Protocol Analyzer the tool of choice for debugging memory protocol issues and for validating proper system behavior. Furthermore, the tool can be used for verification of the command sequencer and the interaction between the DUT and the memory models. The feature, we are going to look at today, is synchronizing transactions to the corresponding signals.
