Ikizamini cya PD ni cyo gipimo cy’ingenzi cyo gupima ibikoresho by’amashanyarazi, kandi gusohora igice ni cyo gipimo cy’ingenzi cy’ubwiza bw’ibikoresho by’amashanyarazi. Iki gikoresho gipima gishingiye kuri modularisation, gishushanya ibice bya simulation nk’uburyo busanzwe bushingiye ku mikorere itandukanye. Module zishobora kongerwamo cyangwa gusibwa uko umukoresha abikeneye. Module ni ubwoko busanzwe bw’Uburayi, bworoshye kubungabungwa no kuvugurura. Gikoresha sisitemu igezweho yo gutunganya ibikoresho, na ikarita ya NI yo muri Amerika National Instrument. Gikoresha kandi ikoranabuhanga ryo kuyungurura n’ibindi bikoresho byo gutunganya ibimenyetso kugira ngo gikusanye kandi gisesengure ikimenyetso cya PD.
