VotaryTech Celebrates its 9th ANNIVERSARY

The hardware design on a broader scale can be divided into two categories: ASIC (Application Specific Integrated Circuit) design and FPGA (Field Programmable Gate Array) based design. ASIC design is more complex and time consuming but cost effective and customizable for volume production. On the other hand, FPGA design is simpler and faster but costly when applied to volumes and hence meant for specific usage.

Typical ASIC design flow with ordered steps:

Design Spec → RTL (Register Transfer Level) coding → Functional/Gate level verification → Synthesis → Design for testability (DFT) → Place and route (P&R) → Static Timing Analysis (STA) → Timing Extraction → GDSII

Typical FPGA design flow with ordered steps:

Design Spec → RTL coding → Functional/Gate level verification → Synthesis → Place and route (P&R) → Static Timing Analysis (STA) → Download on FPGA

At Votary tech, with our talented and experienced team, we provide quality design and verification services to achieve faster time to market. With our software and Hardware skills put together we can provide a complete embedded system.

VotaryTech has extensive resources to provide design verification and validation services spanning analog, mixed-signal, ASIC, SoC, digital logic and custom IP. The validation process includes pre-silicon, post-silicon and system validation.

We apply advanced verification methodologies for projects by aligning them to the client’s process including the use of high-level verification languages like SystemVerilog UVM (universal verification methodology), Verilog-AMS and more.

The modern digital logic verification involves constrained random testing, functional coverage, and assertion-based verification. Our emphasis on both digital and mixed-signal designs enables us to provide experienced engineering resources in mixed-mode simulation methodologies. We also have dedicated engineers experienced with Verilog-AMS (analog-mixed-signal) who create mixed-signal verification environments for advanced mixed-signal ICs. And we have delivered the latest verification environments using the Verilog-A/AMS and RNM Real Number Modeling) for our clients.
