    摘要: A hybrid timing analysis method includes: receiving a pre-layout netlist, a post-layout netlist and a configuration file associated with an integrated circuit design; generating a first measurement script and an input stimulus waveform file according to the configuration file; performing a first dynamic timing analysis upon the pre-layout netlist by using the first measurement script and the input stimulus waveform file to generate a pre-layout simulation result; identifying at least one data path and at least one clock path according to the pre-layout simulation result; generating a second measurement script according to the at least on data path and at least one clock path; and performing a second dynamic timing analysis upon the post-layout netlist by using the second measurement script and the input stimulus waveform file to generate a first post-layout simulation result. Associated system and non-transitory computer readable medium are also provided.

    摘要: A circuit includes a first data line, a second data line, a reference node, and a memory cell. The reference node is configured to have a reference voltage level corresponding to a first logical value. The memory cell includes a data node, a first transistor and a second transistor connected in series between the first data line and the reference node, and a third transistor between the data node and the second data line. A gate of the first transistor is coupled to the data node, and the first transistor is configured to be turned off when the gate of the first transistor has a voltage level corresponding to the first logical value. The third transistor is configured to be turned off when a gate of the third transistor has a voltage level corresponding to a second logical value different from the first logical value.
