Abstract
Configuration information is generated for a configurable mixed-signal system. Analog requirements for operating the configurable mixed-signal system are gathered. A simulation model of a delta-sigma modulator is received. A simulation based on the simulation model of the delta-sigma modulator is performed to obtain parameter settings for the delta-sigma modulator. The obtained parameter settings are used to build at least a portion of a description of the configurable mixed-signal system. The description of the configurable mixed signal system is synchronized to receive configuration information.
