The use of metal fill to improve planarity and to manage electrochemical deposition (ECD), etch, lithography, stress effects, and rapid thermal annealing. Scan chain is a technique used in design for testing. While such high packing densities allow more functionality to be incorporated on the same chip, it is, however, becoming an increasingly ponderous task for the foundries across the globe to manufacture defect free silicon. The objective is to make testing easier by providing a simple way to set and observe every flip-flop in an IC .The basic structure of scan include the following set of signals in order to control and observe the scan mechanism. A scan chain is formed by a number of flops connected back to back in a chain with the output of one flop connected to another. A multiplexer is added at the input of the flip-flop with one input of the multiplexer acting as the functional input D, while other being Scan-In (SI). I was thinking I could have the Design Compiler insert the scan using VHDL instead of Verilog and then I wouldn't have to do a simulation mixing Verilog and VHDL. There are very few timing related defects at these larger design nodes since manufacturing process variations cause relatively small parametric changes that would affect the design timing. In Tetramax after reading in the library and the DFF.v and s27_dft.v files, The multi-clock protocol requires that the strobe time be before a clock's pulse if it is used for transition fault testing.
