What a real ISO 26262 FMEDA work package contains, section by section — failure-rate budget, fault-region partition, SPFM/LFM/PMHF with the actual arithmetic, traceability, and the assumptions that decide whether the numbers mean anything. Includes how to audit a vendor’s FMEDA and the red flags to look for.

RF and Microwave Design: Amplifiers, Mixers, Non-Reciprocal Devices and Antennas
A working engineer’s guide to RF and microwave design — S-parameters and matching, amplifier gain, stability and noise, mixers and spurious products, isolators and circulators, antennas and link budgets, and which solver to use for each. Covers HFSS, CST, Clarity, Momentum, FEKO, ADS harmonic balance, Nexxim, and the measurement discipline that keeps simulation honest.
Power Integrity: From Static IR Drop to Rapid di/dt, Board to Die
A working engineer’s guide to power integrity — static DC drop and current density, the PDN as a frequency-dependent impedance, target impedance, decoupling and anti-resonance, plane cavity modes, and the di/dt events that no amount of bulk capacitance can fix. Covers SIwave, PowerDC, PowerSI, HyperLynx PI, Clarity, HSPICE and the on-die IR/EM signoff tools, plus how to actually measure a PDN.
