Profilazione del tempo di esecuzione del codice

Visualizzare e analizzare i profili del tempo di esecuzione delle sezioni di codice

Utilizzare la profilazione del tempo di esecuzione per:

  • Verificare se il codice generato soddisfa i requisiti in tempo reale dell'hardware target.

  • Determinare le sezioni di codice che richiedono miglioramenti in termini di prestazioni.

È possibile configurare simulazioni Software-In-the-Loop (SIL), Processor-In-the-Loop (PIL) o in modalità esterna basata su XCP per ottenere metriche relative al tempo di esecuzione del codice generato. Utilizzare Code Profile Analyzer, il report sull'esecuzione del codice o Simulation Data Inspector per analizzare le metriche relative al tempo di esecuzione.
