Responsibilities
As an STA Engineer, the day-to-day work involves performing static timing analysis across multiple corners and modes using tools like Synopsys PrimeTime
The role includes maintaining and validating SDC constraints, collaborating closely with RTL, synthesis, and physical design teams to resolve timing issues
Own STA sign-off for block and chip level including custom timing checks
Develop automation scripts in Tcl or Python to streamline analysis and reporting, prepare sign-off quality constraints, and ensure the design meets all performance and reliability targets before tape-out
Qualification
Required
BS and 3+ years of relevant industry experience
Hands-on experience in ASIC timing constraints generation and timing closure
Good knowledge in STA tools (such as Primetime) and methodologies for timing closure with a good understanding of OCV, noise and crosstalk effects on timing
Good understanding and experience in timing closure of various test modes such as scan shift, scan capture, atspeed and BIST testing
Own STA sign-off for block and chip level including custom timing checks
Hands on experience in timing/SDC constraints generation and management
Knowledge of low-power techniques including clock gating, power gating and multi-voltage designs
Proficient in scripting languages (Tcl and Perl/Python)
Strong communication skills are a pre-requisite as the candidate will collaborate with a lot of different groups (e.g. digital design, DFT, physical design, etc.)
Preferred
MS and 3+ years of relevant industry experience
