Version 3.1 (Changes from Version 3.0)
Version 3.1 is a maintenance release that fixes a
few important bugs and minor performance enhancements
Version 3.0 (Changes from Version 2.3)
- The second
generation of our ZEro-Overhead-Stack (ZEOS-II)
technology is introduced in 3.0. The benefits of this simulation
kernel implementation result in up to 8x performance improvement
over release 2.3 for the Professional Edition. The Standard Edition
also features significant kernel performance improvement over
The Professional Edition contains
enhancements that are performed by concurrently analyzing the entire
design hierarchy -- also termed global optimizations. This results
in much higher simulation performance.
The Professional Edition also benefits
from new optimizations for VHDL Vital Level 1 architectures. Most
compilers/simulators do not optimize Level 1 architectures.
You can now control the simulator
resolution to achieve faster simulations. For instance, your gate
level simulations can run twice as fast if you set the simulator
resolution to nanoseconds ("1ns") instead of picoseconds ("1ps").
The default resolution is "1ps" for 3.0. In release 2.3, the
simulator was fixed at femtosecond resolution ("1fs"), which is
typically much higher resolution than the signal switching rates
observable in a real-world design.
Sonata GUI Enhancements
Our fast and efficient waveform viewer
gets even faster. Performance of viewing analog waveforms has been
enhanced. Zooming and scaling analog waveforms is responsive even
with a large number of analog waveforms.
In Sonata's Simulator settings dialog
box, you can now disable SDF annotation. In release 2.3, you had to
delete the entry and then re-enter from scratch when needed. You can
now simply enable/disable each SDF annotation entry.
In the language-sensitive Text Editor,
the character font is now user selectable.
On the Linux platform, you can now
select your favorite HTML browser (default is Mozilla). On Windows,
Sonata always uses the browser registered to handle HTML files.
