• The Democratization of Digital Methodologies for AMS Verification

  Article - Jul 05, 2022 by Sumit Vishwakarma

  A mixed-signal design is a combination of tightly interlaced analog and digital circuitry. Next-generation automotive, imaging, IoT, 5G, computing, and storage markets are driving the strong demand for increasing mixed-signal content in modern systems on chips (SoCs). There are two critical reasons for this trend.

  In this session, you will learn about some of the new syntax and semantic capabilities and clarifications introduced in IEEE1801-2018 (UPF 3.1), typical use cases that prompted the addition or change and highlight any semantic differences with previous versions of the standard where applicable.

• Low Power Considerations for Verification

  Webinar - Apr 29, 2021 by Rick Koster

  Achieving coverage closure increases with the number of power domains in a design. The UPF add_power_state and add_state_transition commands can help bound the verification state space. In this session we will discuss how to use these commands to manage verification.

• Primary, Anonymous, or What? The Destiny of Ports from Design Top from Off-Chip

  Webinar - Mar 31, 2021 by Progyna Khondkar

  This session distinctively studies the ‘simulation-impacting’ features of ‘design top’ IOs and the effect of each feature on verification results; this has been accomplished by thoroughly identifying every possible scenario for different design tops, their port types, possible LRM interpretations, presence of design or liberty or UPF attributes, and repercussions at post synthesis simulation.

• Bringing Reset and Power Domains Together – Confronting UPF Instrumentation

  Webinar - Mar 31, 2021 by Abdul Moyeen

• Bringing Reset Domains and Power Domains Together - Confronting Issues Due to UPF Instrumentation

  Resource (Slides) - Mar 31, 2021 by Abdul Moyeen

  The Unified Power format (UPF) standard enables designers to add power intent for the design. For power management designers typically partition design into power domains. Interactions between these power domains are done through various power control logics like retention logic, isolation logic, level shifters, etc. Designers need to validate that the power control logic does not introduce new multi-clock and multi-reset issues into the design.
