A recent article from Semiconductor Engineering, titled "Build Secure SoCs From The Start," makes the case that security cannot be an afterthought in system-on-chip (SoC) design. The piece argues that hardware vulnerabilities are best prevented when security is considered from the earliest architectural stages, rather than bolted on after the design is complete.
The article points to the growing complexity of modern SoCs and the need for design teams to weigh security alongside power, performance, and area. It emphasizes that early choices about the chip's structure, memory isolation, and access controls can have long-lasting consequences for how well the device resists attacks.
By treating security as a foundational requirement, design teams can reduce the risk of expensive respins or difficult field patching. The source article stresses that secure SoCs are not built by adding protections at the end, but by embedding them into every layer of the design flow.
