Summary
👤
Senior🎓
Top SchoolChristian Costa is a seasoned Digital Physical Implementation Engineer with 14 years in semiconductor systems design and firmware, currently delivering MoCA network HW IP and SoC physical implementation at STMicroelectronics in Grenoble. He bridges digital and analog domains, taking mixed-signal SoCs from RTL through synthesis, place-and-route, and signoff while driving flow, methodology and automation including FPGA prototyping. His background spans firmware and HW roles—H.264 encoder DSP work, TV demodulation IP, and early USB/60 GHz transceiver FPGA design—giving him uncommon depth across verification, RTL-to-GDSII implementation, and low-power connectivity IP. An active contributor to open-source graphics compatibility (Wine d3dx9 fixes and RTX 3070 support), he combines practical system-level engineering with hands-on debugging and toolchain development. Comfortable leading small software teams and technical projects, he brings a pragmatic, tool-oriented approach to complex mixed-signal integration and performance optimization.
