Not exactly. Post 1990s when Iranian IR-2/2M came into being and onwards towards IR-4/4M, IR-6 and IR-8/9 now at 25 SWU, all of these have nothing to do with pakistan or actual original European Designs (Dutch-German URENCO gave birth to both Iran and Pakistani enrichment). Not even a single shred of evidence exists since.
Dr. Abdolghadeer Khan took German-Dutch Urenco patent of G1 and V1 centrifuges from his job, these patents became P-1 and IR-1 in Pakistan and Iran in 1980s. Beyond that no connection between two state's nuclear program exists. Iranian program under Dr. Fakhrizadeh moved to C-fiber centrifuges in 1990s with IR-2/2M which is unique to Iran, even patented under Fakhrizadehs name.
This is the IAEA published time based data structure of Iranian Centrifuges, once can see the native designs taking over around 1990s.
