New Horizons

Welcome to my blog

My name is Sven Andersson and I
work as a consultant in embedded
system design, implemented in ASIC
and FPGA.
In my spare time I write this blog
and I hope it will inspire others to
learn more about this fantastic field.
I live in Stockholm Sweden and have
my own company

FPGA design from scratch. Part 9
When we have a stable design it is time to start the regression testing. We have to put together a test suite containing all the testcases we would like to use for our functional simulation. When we run all these testcases we will produce a lot of test result log files. We need a system to handle the whole regression testing and the Mongoose Simulation Environment can help you.

Regression Testing in Mongoose

Mongoose uses test sequences written in the Mongoose
Script Language (MSL) to perform regression testing. A  test sequence is a collection of testcases that are executed in sequence. You can control when to start a new testcase and where to send it. It can run as a background job on your own host or it can be sent to a batch queue manager (LSF) and  run on a dedicated simulation host.
This flow diagram shows the process of generating a test sequence, running a test sequence, analyzing the result and display the result in a web browser and/or send an email or
SMS with a summary of all test results.

Here is an example of a test sequence file. You can mix unix commands and Mongoose script commands. Lines starting with UC: are a unix commands and lines starting with MC: are Mongoose commands. You can write this file by hand or you can use the Test Sequence Generator to automatically generate one from the testcases you selected.

// Module:        ETC_TEST
// Design:        ETC
// Written by:    Sven-Ake Andersson ZooCad Consulting
// Description:   Test sequence file used for regression runs 

UC:echo 'Start test sequence'
MC:SetTestCounter 1
MC:SetTagName ETC
MC:SelectLogFile On
MC:SetReleaseName today
// Start of test sequence
UC:echo 'Testcase running :'
MC:WaitSeconds 20
MC:WaitForSimulationToFinish 100
UC:echo 'Testcase running :'
MC:WaitSeconds 20
MC:WaitForSimulationToFinish 100
// Add more testcases here
// ..................
// Stop routine

UC:echo 'End of test sequence'
MC:SendSMS 0706420380

This is the email and SMS message sender window.

After running our testcases we have all
simulation log files saved in the result/printout directory:

Let's use the Log File Analyzer/Test Report Generator to generate a condensed test report file.

The Test Report Generator will search all log files for important information and put it into the
report file. The two errors reported are from testcases testing a function not implemented and can be ignored. We are finally ready for implementing the design into the FPGA.

Here is the email sent from the Mongoose script:
