There is a good article about Numerical Rounding on Wikipedia for reference. The idea about the tie-breaking technique round-to-even is, to round a fractional number to the nearest even, in case the tie 0.500 appears. So the value 3.5 will be rounded to the integer number 4 and 2.5 will be rounded to the integer 2. A tie is considered the fractional part 0.5… text/html 2010-07-16T07:49:22-05:00 Guenter Dannoritzer http://www.myhdl.org/doku.php/projects:sidebar?rev=1279284562&do=diff * Welcome to MyHDL * Users & Projects * Thomas Traber * How to connect eispice and MyHDL * Cordic Calculations * Sine Wave Generator using Sigma Delta DAC * Cosimulation using Quartus Simulator * Interactive Simulation with IPython text/html 2010-07-16T06:25:18-05:00 Guenter Dannoritzer http://www.myhdl.org/doku.php/projects:intro?rev=1279279518&do=diff This page lists a number of MyHDL users and projects.

This page contains detailed instructions for installing MyHDL on a typical Linux or Unix system. For other platforms, you have to follow an equivalent procedure. Remember that MyHDL can be installed on any platform that supports Python. For more information about installing on non-Linux platforms such as Windows, read about Installing Python Modules. text/html 2010-06-21T11:32:30-05:00 Jan Decaluwe http://www.myhdl.org/doku.php/dev:sidebar?rev=1277137950&do=diff * Welcome to MyHDL * The Development Zone * Introduction * Source code repository * Contributing changesets * Development snapshots * Open tasks * MyHDL 0.7 * Ideas and Draft Proposals * myhdl.org * VHDL Cosimulation with GHDL text/html 2010-06-21T11:13:43-05:00 Jan Decaluwe http://www.myhdl.org/doku.php/faq?rev=1277136823&do=diff Modeling What is the default bit width of an intbv object? By default, an intbv object has an “indefinite” bit width. Although this is a novel concept compared to traditional HDL modeling, it corresponds to the natural way to think about integers and their 2's complement representation. Consider:
