CSim: A MOS Switch-Level Simulator
نویسندگان
چکیده
We develop a new switch-level simulator, CSim, for MOS transistor cells. CSim simulates cells without circuit parameters, such as the sizing of transistors. To tackle the challenges caused by the lack of circuit parameters, a new transistor-level levelization algorithm is developed. SPICE simulator is used as reference simulator, CSim is accurate in a sense that the simulation results for a cell are consistent with SPICE simulation results for any transistor sizing configurations. The program was tested on all possible cells up to 4 transistors and was able to report accurate results for all levelizable cells.

Symbolic Verification of MOS Circuits
The program MOSSYM simulates the behavior of a MOS circuit represented as a switch-level network symbolically. That is, during simulator operation the user can set an input to either 0, 1, or a Boolean variable. The simulator then computes the behavior of the circuit as a function of the past and present input variables. By using heuristically efficient Boolean function manipulation algorithms,...

متن کاملOn the Use of Multiple-Valued Switch-Level Algebra to Analyze Binary MOS Bridge Circuits and Dynamic Circuits
This paper presents two new results for multiplevalued switch-level algebra (MSA for short). The first is the use of MSA to descaibe the bidirectional switching function of MOS transistors and, thereby, to analyze binary MOS bridge Circuits. The second is the use of MSA to describe the function of capacitors and, thereby, to analyze binary MOS dynamic circuits. The results presented in this pap...
