Engineering – Silicon Engineering /

Full-time /

Hybrid

Own the implementation of block level subcomponents and their physical integration into the

top level of a system-on-a-chip (SoC). The design cycle will start with synthesis of various

hierarchies to translate a High Level Description Language view of the functionality (Verilog

RTL) into a Gate Level Description (Verilog netlist). Take the netlist through the various steps

of a Place and Route flow (PnR) to produce manufacturable database (GDS) that meet all the

requirements of performance, power, and area specifications of the final product. Optimize floor

plans to integrate intellectual property cores and subsystems from internal groups and external

partners to achieve the smallest footprint area while satisfying all electrical integrity

requirements. Generate physical and timing constraints for sub-block implementation. Design,

implement, and analyze high frequency clock distribution networks at the top and block level to

enable communication between synchronous elements. Design, implement, and analyze high

performance interfaces between subsystems of the SoC for high speed communication. Analyze

and close timing by implementing design changes and fine-tuning of critical timing paths to

ensure the part operates at the target frequency. Run physical verification and implement fixes

to satisfy the design rules established by the chip foundry. Contribute to the automation of the

PnR flow by writing code in industry standard scripting languages to add customization and

collect metrics.

Owned partitions/blocks of a E-core CPU and took it through the various steps of a Place and Route flow (PnR) to produce manufacturable database (GDS) that meet all the requirements of performance, power, and area specifications of the final product.
Analyzing and closing timing by implementing design changes and fine-tuning of critical timing paths to ensure the part operates at the target frequency.
Optimizing floor plans to achieve the smallest footprint area of a given block (2M+ to 4M+ gates) while satisfying all electrical integrity requirements.
Performing physical (pin placement) and timing constraints for sub-block implementation. Designing, analyzing and implementing high frequency clock distribution networks at the block level.
Owning flow updates and contributing to the automation of the PnR flow by writing code in industry standard scripting languages to add customization and collect metrics.
Working on full chip timing analysis and closure, including performing distributed timing analysis, ECO generation and timing model generation for hand off to SOC teams.
