EDT (Embedded Deterministic Test )嵌入式确定性测试,是一种测试手段,作用是将数量庞大的scan chain通过压缩、解压缩形成数量较少的scan channel并通过scan channel与外部进行交互。通常会产生三部分结构:Decompressor(解压缩器)、Compactor(压缩器)、Bypass(旁路模块)。 压缩比/解压缩比 压缩比指的是内部scan chains的...

1. 输入/输出的Channel数目:Channel的数量直接关系到信息的传输和处理能力,因此与压缩率紧密相关。 2. Shift Cycle:这主要取决于Scan Chain的长度以及低功耗设置。更长的Scan Chain或特定的低功耗设置可能会影响压缩的效率, 一般为平均链长+low power shift。(小思考?shift cycle的count能否增加EDT的随机序列的控制...
It employs a controller that either allows a given scan chain to be driven by a power-aware EDT decompress or, or by a constant value fixed for the entire scan load. The controller's configuration is held constant for all cycles of a given scan load but is reloaded for every pattern ...
