Zhang Haijun / 张海军

Zhang Haijun / 张海军 is the guest in 华为的「韬定律」，是创新还是噱头？｜ Bonus, where he is introduced as a former senior engineer at Synopsys / 新思科技 and the author behind the public account “福利业的猫.” In the episode, he explains Huawei’s Tau Law from a semiconductor-engineering and [[ElectronicDesignAutomation|EDA]] perspective.

His key contribution is the distinction between ordinary die-to-die Semiconductor 3D Stacking and the more ambitious Cell-to-Cell Logic Stacking implied by Huawei’s logic-folding language. Zhang treats Tau Law as meaningful but not proven: the metric shift toward system time is reasonable, while the cell-level implementation still needs new tools, packaging capability, and product evidence.
