It was 2004, and three of our founders were attending an international symposium they organized on Clockless Computing (Coordinating Billions of Transistors), at Washington University in St. Louis, Missouri.  In the program, leaders in asynchronous computing reviewed future design challenges imposed on IC densities according to Moore’s Law.

MetaACE LTD is a free, node-limited version of the MetaACE metastability analysis tool. MetaACE LTD provides all of the features of MetaACE except that it is limited to evalua- ting circuits with less than 250 nodes. Experience shows that many synchronizers can be evaluated quite well by including only bulk capacitance in the extracted netlists. Meta ACE LTD allows many synchronizers to be evaluated with results typically within 5-10% of true behavior. Users can use MetaACE LTD to evaluate their designs, quickly, and use the same conguration files in the professional version of MetaACE for highly accurate simulations of fully extracted netlists.


The Clock-Domain-Crossing Conundrum

– Jerry Cox The Clock-Domain-Crossing conundrum is this:  Where is the evidence of Clock-Domain-Crossing (CDC) failures that have occurred during a product’s service life? We know there have been products that have had CDC failures during test and been re-spun, revised or abandoned before being put into service. Theory predicts there must also be products…


Synchronization and Metastability

Steve Golson Trilobyte Systems ABSTRACT The phenomenon of metastability is inherent in clocked digital logic. Many techniques have been presented for minimizing metastability, both for crossing clock domains, and for handling asynchronous inputs. Some of these “best practices” have unexpected weaknesses and must be used carefully, particularly at smaller process nodes. This paper will explore…
