TDML and the Free Timing Diagram Viewer
SynaptiCAD provides a free TDML and BTIM
viewer for viewing timing diagrams created by Data Sheet
Pro, WaveFormer Pro, TimingDiagrammer Pro, and other TDML
editors. This lets design engineers quickly evaluate
potential components for critical timing constraints and
clock speed compatibility. The timing diagram editing
environment of the free viewer lets an engineer perform
what-if analysis and enter or merge his design constraints
with a component's timing diagram. With a professional
version of WaveFormer Pro, he can also export his timing
diagrams directly as stimulus vectors and HDL models and
use them with HDL and gate-level simulators.
IP vendors are also gearing up to release
transaction protocols as TDML timing diagrams. For
designers, one of the major challenges to using IP is to
determine a method for communicating with the IP block.
Timing diagrams provide a concise visual description of
cause-effect relationships between transaction events and
have long been used to describe the rules that must be
followed for successful communication with an IP block.
TDML provides an open format for distribution of protocol
specifications, enabling IP vendors to release complete
interface information without locking their customer base
down to a specific EDA tool suite.
