New versions of Icinergy's design exploration tools introduce new capabilities for early physical planning of systems-on-a-chip (SoCs) and ASICs. SoC Preview ($9500) now can quickly generate .pdf datasheets for side-by-side comparison of alternative combinations of intellectual-property blocks, macros, and process technologies. SoC Plan ($20,000) includes interactive floorplanning, I/O placement, and interconnect planning facilities. SoC Prototype ($35,000) adds timing-driven block placement and automatic generation of synthesis constraints. Visit www.icinergy.com.
