In the light of the growing popularity of mixed, analogue and digital ASICs and System on Chip, several high level hardware description languages (HDLs), such as VHDL and Verilog, have recently been extended to provide analogue and mixed-signal (AMS) modelling capabilities. SystemC is a new language added recently to the existing HDLs used by the digital electronic design community. In this book a novel methodology has developed that enables the extension of SystemC to the analogue domain and allows simulations of mixed-signal and mixed-domain systems on arbitrary levels of abstraction. The developed AMS extension is named SystemiA and complies with SystemC semantics. In many respects, SystemiA is more powerful than many existing HDLs.
