Abstract

A method of operating a delay-compensated simulator and an apparatus for performing the method are provided. The emulator includes: a memory for storing a first netlist, a timing library, and a standard parasitic exchange format (SPEF) file; and a processor configured to compensate for delays to synchronize digital and analog signals. The processor includes: a delay calculator module for generating one of rise time and fall time and a Standard Delay Format (SDF) file using the first netlist, timing library, and Standard Parasitic Exchange Format (SPEF) file; the SDF file a converter module for adjusting an interconnection delay description included in the SDF file to compensate for the delay using said one of the rise time and the fall time; and a digital simulator module for utilizing the compensated interconnection delay description based on the compensated interconnection delay description The first drive unit generates an event.

Description

[0001] Priority is claimed on Korean Patent Application No. 10-2014-0142459 filed with the Korean Intellectual Property Office on October 21, 2014, the entire contents of which are hereby incorporated by reference. technical field [0002] Embodiments of the inventive concept relate to a method of operating a simulator, and more particularly, to a method of operating a simulator and a simulation device for performing the method, wherein the simulator is capable of including a The interconnect delay description in the (SDF) file compensates for the synchronization of the digital signal with the analog signal. Background technique [0003] Electronic Design Automation (EDA) is a technology for designing and producing electronic devices ranging from printed circuit boards (PCBs) to embedded circuits. Mixed-signal simulation tools for EDA are commonly used to verify semiconductor designs such as semiconductor memory or system-on-chip (SoC). [0004] Mixed-signal simulators may ...
