Prototyping tool enables schematic IP
re-use
Zuken has upgraded its Hot-Stage virtual prototyping tool to enable electrical constraints to be defined and re-used within a schematic capture environment.
Zuken has upgraded its Hot-Stage virtual prototyping tool to enable electrical constraints to be defined and re-used within a schematic capture environment Hot-Stage 4.03 enables definition of high-level metaconstraints for complete signal paths within the schematic, each constraint being capable of application to different design hierarchy levels

Zuken joins the Synopsys HSPICE Integrator Program
Zuken has joined the Synopsys HSPICE Integrator Program to advance its high-speed design flow and increase capabilities for simulation of highly complex electronics circuits.
Hot-Stage has always allowed users to establish electrical and physical constraints from a central database of information, but only logical attributes could be defined within the schematic.
Effective IP re-use requires the ability to capture not only logical net constraints, but also the constraints associated with electrical nets and complete timing paths.
Fig.1 illustrates the point.
At the schematic level, engineers have always been able to specify delays for logical nets N1 and N2, but have not been able to specify overall path delays.
Such low-level attribute definition leads to overconstrained routing, particularly in high-speed designs.
The new metaconstraints in Hot-Stage 4.03 eliminate this problem, avoiding unnecessary router rip-ups and ensuring that schematic design re-use can be achieved without redefining attributes and constraints for every net.
Design time can be significantly reduced and routing optimised for each signal path.
Hot-Stage, part of Zuken's Board Integrity Solution for PCB design, gives engineers a virtual scratchpad for design experimentation within a constraints-driven environment including accurate placement, routing and simulation of high-speed circuits.
This leads to right-first-time boards and dramatically reduced development time.
A "companion" version of the tool provides the same functionality for users of Mentor's Board Station layout package. Request a free brochure from Zuken ...
