Excellicon’s new Budgeting-Toolbox provides a very comprehensive solution for timing budget generation and analysis as part of timing closure

Laguna Hills, CA.
Excellicon Inc. an innovative provider of comprehensive end-to-end timing constraints, CDC and clock analysis products announced release of its latest product “Budgeting Toolbox” platform for generation and analysis of timing budgets from very early RTL stage to final tape-out.
Budgeting Toolbox (BT) empowers the designers to perform hierarchical budgeting with varying levels of accuracy spanning from RTL to Physical domain. The product has full capabilities for budget generation, Verification and subsequent refinement, hierarchical budget management, automatic redistribution of timing budgets, as well as most powerful physical budgeting which derives the budgets using floorplan information and manages the budgets throughout the timing closure cycle including the creation of timing models, leading to final iterations before tape-out.
Timing budgets need to constantly change as design matures during the physical implementation. This includes RTL changes, to ECO’s, which may each result in imbalances of timing among various blocks in the design, which needs to be adjusted to address the timing violations between the blocks. Designers have to find a way to redistribute the budgets to address the timing of failing paths; an exercise done manually which results in long iterations and often sub optimal timing for the chip.
With teams of physical implementation engineers working in parallel on their own blocks, the interface timing must account of accurate budgets in order for the top level timing to pass without any violation. Excellicon’s BT offers a comprehensive solution of not only validating the correctness of existing budgets across the blocks, but also generates the appropriate budgets at each phase of the implementation cycle, from percentage based delay budgeting to logic levels and finally using the actual cell delays with parasitic information from the layout.
“Existing timing budgeting tools generally use a percentage or level of logic based budget calculation approach to distribute timing budgets across various blocks and hierarchy levels. However in order to accurately estimate the timing budgets for the RTL to physical world, there is a need for much detailed and accurate timing budgets which can only be achieved by taking the physical information into account. Excellicon solution will allow our users the flexibility to specifically target areas of concern to achieve the best timing results”, said Himanshu Bhatnagar, CEO of Excellicon. “We believe with our latest offering of Budgeting Toolbox we can plug yet another huge gap in addressing the timing closure of a design.
The Budget Toolbox offering will position Excellicon as the only company which can perform the most difficult budgeting needs of designer. Budget Toolbox is being shipped as an add-on to ConCert product.
Excellicon is an innovative provider of comprehensive end-to-end Timing Constraints Analysis and Debugging solutions for the automation of constraints authoring, completion, and validation from RTL to GDS with innovative analysis and debugging infrastructures. Excellicon products CONMAN, CONCERT, ConDor, ConCert-ET (Exceptions Toolbox), and Budgeting ToolBox address the needs of designers at every stage of SOC design and timing closure and implementation in a unified environment. – Timing Closure; Done Once! Done Right!
