Virtual EMI/EMC Laboratory - Enabling Earlier EMI Visibility using Compliance-Scope
Compliance-scope enables Virtual EMI/EMC Laboratory, a simulation-based approach that enables engineers to investigate electromagnetic interference mechanisms earlier in the hardware development process. By replicating standardized EMC compliance test environments in simulation, engineers can analyze emission or immunity behavior, diagnose root causes, and evaluate mitigation strategies before hardware prototypes enter physical testing. This approach provides earlier EMI visibility and supports a more proactive design-for-EMC workflow
INJECTION PROBE MODELS FOR COMPSCOPE
The Bulk Current Injection (BCI) method is widely used for RF immunity testing of automotive systems. If detected at a late stage, compliance failures may lead to expensive redesigns and increased time to market. Therefore, it is desirable to evaluate the chip.
BCI CALIBRATED POWER AND SCALING FACTOR
The Bulk Current Injection (BCI) method defined by ISO11452-4 [1] is widely used for testing the immunity behavior at the component or module level. Figure 1 depicts a general BCI test bench. The two test methods defined in the standard are: the open-loop (substitution), and closed-loop (current monitoring probe) methods. DUT current defines the calibrated power.
