Staff/Principal Engineer - HDL Simulation

Job Description

Softnautics is looking for someone willing to work as a HDL modelling expert in addition to mastering the FPGA architecture. The individual will work on developing cycle accurate, fast simulation models for various FPGA blocks like basic cells, RAMs, PLLs, highspeed transceivers, and other functional blocks. The individual must have strong knowledge on Verilog/System Verilog, FPGA simulation, AMBA protocols and FPGA architecture. In addition, the individual must also be able to work in fast-paced, high demand, multiple-deadline drive environment.


  • Develop behavioural HDL models for various FPGA functional blocks like basic logic cells, RAM, PLL, SerDes, etc.
  • Focus on developing cycle accurate and fast HDL simulation models by using Verilog/System Verilog HDL
  • Debug on customer issues, bug-fixing, and maintenance of simulation models
  • Analyse the simulation models and make implementation choices to optimize the simulation run time, memory utilization etc.
  • Simulation library generation and qualification through regressions
  • Perform pre-synthesis, post-synthesis, and Back Annotated (BA) simulation
  • Work with other teams to get BA simulation data (sdf) and add it in simulation model
  • Read and understand the Silicon Architecture specifications
  • Should be able to estimate the efforts and provide the plan for completing the requirements
  • Propose / review test plans and reports
  • Assist and train Juniors engineers in the team

Skill set
