The article has a mistake. The first fugure is not C-element. Muller-Bartky theory supposes 1 equation = 1 element = 1 delay. On the figure it is shown 1 equation and 4 elements with 4 delays. In addition analysis of this 4-elements circuit shows that it is not semimodular. The circuit is not speed-independent, hazards may occure on the upper and lower elements on the figure. 126.96.36.199 (talk) 15:31, 19 June 2010 (UTC) L.P.Plekhanov, IPI RAN, Russia firstname.lastname@example.org
I made some drawing about C-elements. They are used in the french article. There are the classical static and semi-static implementations, and the implementation with 4 nand gates, which is more accurate than with 3 AND and an OR, since it is more efficient in CMOS.
I will probably modify this article soon. I should perhaps reunite the different drawings, as it is currently the case, since it would be easier to read _ but harder to reuse.
