A scheme for multi-frequency at-speed logic Built-In Self Test (BIST) is provided. This scheme allows at-speed testing of very high frequency integrated circuits controlled by a clock signal generated externally or on-chip. The scheme is also applicable to testing of circuits with multiple clock domains which can be either the same frequency or different frequency. Scanable memory elements of the digital circuit are connected to define plurality of scan chains. The loading and unloading of scan chains is separated from the at-speed testing of the logic between the respective domains and may be done at a faster or slower frequency than the at-speed testing. The BIST controller, Pseudo-Random Pattern Generator (PRPG) and Multi-input Signature Register (MISR) work at slower frequency than the fastest clock domain. After loading of a new test pattern, a clock suppression circuit allows a scan enable signal to propagate for more that one clock cycle before multiple capture clock is applied. This feature relaxes the speed and skew constraints on scan enable signal design. Only the capture cycle is performed at the corresponding system timing. A programmable capture window makes it possible to test every intra- and inter-domain at-speed without the negative impact of clock skew between clock domains.

The invention discloses a fast CRISPR-Cas9 working efficiency testing system and application thereof. The testing system comprises a plasmid used for expressing sg RNA, a plasmid used for expressing Cas9 and a reporting system used for testing the CRISPR-Cas9 gene editing efficiency; the reporting system can splice the C-terminal of a nucleotide segment capable of coding effective protein and the N-terminal of a reporter gene and insert two restriction endonuclease enzyme digestion sites into the splicing position; before a special gene is edited (knocked out) through the CRISPR-Cas9 system, selection of a target sequence is vital, and the selection can influence the recognition efficiency of the sg RNA to target DNA, the binding efficiency of the sg RNA with the target DNA, the targeted cutting efficiency of the Cas9 and the NHEJ repairing efficiency. According to the system, the gene editing efficiency of different sgRNA-target DNA sequences can be quantitatively compared, the sgRNA with the best working effect can be determined within a short time, the actual knockout success rate is increased, therefore, the working cost can be lowered, the working efficiency can be improved, and the working progress can be promoted.
