NI Multisim NI Multisim (formerly MultiSIM ) is an electronic schematic capture and simulation program which is part of a suite of circuit design programs, along with NI Ultiboard. Multisim is one of the few circuit design programs to employ the original Berkeley SPICE based software simulation. Multisim was originally created by a company named Electronics Workbench, which is now a division of National Instruments. Multisim includes microcontroller simulation (formerly known as MultiMCU), as well as integrated import and export features to the Printed Circuit Board layout software in the suite, NI Ultiboard. Multisim is widely used in academia and industry for circuits education, electronic schematic design and SPICE simulation. History Multisim was originally called Electronics Workbench and created by a company called Interactive Image Technologies. At the time it was mainl...
Dual Sim A dual SIM mobile phone is one that holds two SIM cards. Dual SIMs are popular in locations where lower prices apply to calls between clients of the same provider; they also allow separate numbers for personal and business calls on the same handset. Devices that use more than two SIM cards have also been developed and released, notably the LG A290 triple SIM phone,and even handsets that can run on four SIMs, such as the Cherry Mobile Quad Q70. History The first phone to include dual SIM functionality was the Benefon Twin, released by Benefon in 2000. It wasn't until the late 2000s, however, when more dual SIM phones entered the marketplace and started to attract mainstream attentio...
