Where is Logic Analyzer used?
Embedded System Testing :
Embedded Systems have multiple devices and each of the devices uses the bus to communicate with the main chip or processor and other devices in the system. The Embedded system generally has SPI and I2C devices to communicate with the main processor. A logic analyzer can be very useful to debug and validate the embedded system and figure out failures of any of the devices in the embedded system.
Post-silicon validation:
During the chip development process, Once the Chips is back from the foundry all the interface of the Chip or SoC needs to be tested. Most of the SoC or chips have I2C, SPI, and UART interfaces. The logic analyzer is a very handy tool for the hardware validation engineer to debug all the various digital channels of I2C, and SPI failures.
Pre-Silicon validation:
In chip or SoC development, before the chip is taped out its engineering manager needs to get the confidence development of the chip, Emulation platforms like Zebu or Palladium are commonly used to do the hardware validation. A logic analyzer can be a very useful assist tool for the emulation engineer to check for the sanity of the communication interface like I2C and SPI along with the emulation Platform.
What are the various Features of a Logic analyzer?
Logic Analyzer comes with the following features:
- Channel Count: The maximum number of digital channels supported by the logic analyzer. The more the channels the more debug capability.
- Triggering: Each of the logic analyzers and equipped with various kinds of triggers, multi-level triggers, multiple consecutive event triggers, etc.
- Sample Rate: This is defined by the maximum frequency that can be measured by the logic analyzer.
- Channel Bandwidth: The logic analyzer needs to have the ability to capture glitches, setup, and hold time issues in the embedded design. The lower the resolution of measurement by the logic analyzer the better the issues that can be captured in the design.
How to integrate a Logic analyzer in the Development Environment?
The Channels which are being measured need to be connected directly to logic analyzer probes. The logic analyzer also provides access to API libraries. These APIs can be integrated into the development environment and an advanced level of validation and testing can be achieved.
