ZedBoard FPGA-in-the-Loop: HDL Verifier vs HDL Coder
Teams asking for FPGA-in-the-Loop on a ZedBoard usually name HDL Coder and SoC Blockset. FIL is actually HDL Verifier. Here is the correct product split, the JTAG versus Ethernet decision, and the 2015-era advice that is still sending Indian teams down the wrong path.
FADOS Test Reports and GSAS Agent: Turning Board Test Results into an Auditable Record
A pass or fail on the FADOS screen is not a record. This guide covers what the FADOS test report contains, what GSAS Agent does with it, and how offline, Google Drive and LAN modes put a QR-linked report on the job card for repair shops and EMS lines in India.
Test Case Design with the Classification Tree Method: Deriving Unit Tests You Can Defend in an Audit
Ad-hoc test cases can be perfectly good tests and still fail an audit, because nothing on file records why that particular set was sufficient. The Classification Tree Method derives test cases from the input space instead: identify the test-relevant aspects as classifications, partition each into equivalence classes, then combine leaf classes in a combination table. Razorcat implements CTM in the Classification Tree Editor, available integrated into TESSY or standalone. GSAS Micro Systems is the authorized Razorcat engineering partner for India, the UAE and Sri Lanka.
Fault Injection and Robustness Testing for Embedded Software: What ISO 26262, IEC 61508 and DO-178C Actually Ask For
Every safety-related unit contains code that correct inputs never execute: range checks, error returns, timeouts, recovery paths. The functional safety standards require that code to be verified, and they are explicit about how. ISO 26262-6 lists fault injection test as a method for both software unit verification and software integration verification; IEC 61508-3 recommends defensive programming from SIL 2 upward and then concedes that defensive code is exactly what stops teams reaching 100 percent structural coverage. This guide separates robustness testing from fault injection, maps each to the obligation that asks for it, and shows how Razorcat implements automated fault injection in TESSY without leaving instrumentation in production code.
How to Evaluate a Unit Testing Tool for Embedded Software: A Buyer's Framework for Indian Teams
Unit test tool evaluations rarely fail on features. They fail because the tool cannot drive the compiler and debugger the project is already committed to, or because the evidence it produces sits outside the scope of the certificate the assessor asks for. This is a buyer-side framework: six questions, what a credible answer looks like in vendor documentation, and a four-week pilot that measures the answers instead of accepting them.
Is 100% Code Coverage Enough? Statement, Branch, MC/DC and MCC, and What Each One Proves
No. A coverage percentage records which code your tests executed, not whether your tests would notice if that code were wrong. This guide defines statement, branch, decision, condition/decision, MC/DC and multiple condition coverage precisely, sets out what 100% of each does and does not prove, shows what ISO 26262, IEC 61508 and DO-178 ask for alongside coverage, and explains the three things to add: requirements traceability, fault-based testing and robustness cases.
