In aceasta lucrare este descrisa topologia celui mai intalnit model pentru simularea descarcarii electrostatice.
Optimizarea circuitului ce reproduce corpul uman este o abordare in plina evolutie ce implica analiza deteriorarilor
echipamentelor electronice. Articolul propune modelarea evenimentului de descarcare electrostatica generata de modelul
corpului uman utilizand un model realistic ce include toate elementele de circuit ce pot fi implicate in proces. Reprezentarea
schematica a modelului corpului uman ca generator de sarcini electrice nedorite se face utilizand tehnici avansate de
instrumentatie viruala. Simularea in programul SPICE, folosind o arhitectura specifica, permite intelegerea comportamentului dispozitivelor supuse testarii sub actiunea diversilor stimuli externi, in speta corpul uman. Testele au condus la concluzia ca
descarcarea electrostatica provenita de la corpului uman produce nivele ridicate ale curentilor de descarcare putand cauza deteriorari serioase ale echipamentelor electronice.

Abstract
In this workpiece is described the topology of the most common model for electrostatic discharge simulation. The
HBM model optimization is a evolutionary approach that involves electronic equipment failure analysis. The present article
proposes modeling the HBM ESD event using a realistic model, including all the circuit elements that may be involved in the
process. Schematic representation of human body model as electrical charges generator is realized using advanced virtual instrumentation techniques. SPICE simulation, using specific architecture, allows understanding the behavior of devices under test at different external stimulus, in this cause the human body. The test concluded that the electrostatic discharge from the human body produces high levels of discharge currents being able to cause serious damages of electronic equipments.
