DiaSIM

DiaSIM_small

DiaSIM’s simulation technology is powered by Sideline Software’s NL5 simulation software. The unique nature of NL5 allows true simultaneous simulation of digital blocks and analog circuit elements. Most PSPICE-based simulations programs cannot simulate true digital circuits with analog components and rely upon approximations of the digital blocks instead of the actual circuit. Dialog’s digital controller technology and advanced analog designs can be accurately simulated thanks to NL5’s powerful technology. For more information, visit Sideline Software’s website.
