In a previous paper we developed a general theory of input/output logics. These are operations resembling inference, but where inputs need not be included among outputs, and outputs need not be ...

As today’s designs become more complex, so too do their constraints. Design functionality typically gets a lot of attention – through code review, functional verification, etc. However, the ...

The INEST= (or INVAR=, or ESTDATA=) input data set can be used to specify the initial values of the parameters defined in a PARMS statement as well as boundary constraints and the more general linear ...

Signoff of a system on chip (SoC) or IP design has multiple aspects, but often timing closure is the most challenging. Early use of a static timing analysis (STA) tool is clearly important, and such a ...

In FPGA design, where timing is everything, there are tips and tricks to help designers set up clocks, correctly set timing constraints and then tune parameters of the FPGA, write Angela Sutton and ...

Many people can recall shocking news images of Japan sustaining earthquake damage. Between 1996 and September of 2018, there were 155 earthquakes in Japan that resulted in human injuries. In 20 of ...
