A computing system may include an electronic design automation (EDA) data constructor engine and an EDA executor engine. The EDA data constructor engine may be configured to perform, using the local resources of the computing system, a data preparation phase of an EDA procedure for a circuit design. The EDA executor engine may be configured to acquire remote resources for an execution phase of the EDA procedure, wherein the remote resources include remote compute resources and remote data resources remote to the computing system; broadcast constructor data constructed from the data preparation phase of the EDA procedure to the acquired remote data resources; and manage performance of the execution phase of the EDA procedure by the acquired remote compute resources and remote data resources.

Hybrid performance of electronic design automation (EDA) procedures with delayed acquisition of remote resources

This application discloses a computing system implementing one or more tools or mechanism configured to capture a hierarchy of a circuit design layout generated by a downstream tool. The hierarchy can include multiple cells that identify corresponding portions of the circuit design layout. The tools or mechanism can be further configured to modify the circuit design layout based, at least in part, on the captured hierarchy, which alters the portions of the circuit design layout identified by the cells separately from other portions of the circuit design layout.

Hierarchical fill in a design layout

Disclosed are representative embodiments of methods, apparatus, and systems for voltage-related analysis of layout design data. According to embodiments of the disclosed technology, voltage association data objects are generated for drawn layers in a net of a layout design and voltage values or ranges of voltage values associated with the net are collected. The voltage values or ranges of voltage values are then associated with the voltage association data objects. A voltage-related analysis may be performed by searching the voltage association data objects according to a predetermined criterion.
