Appendix A. HDL Attributes for Synplify
Using these HDL attributes, you can assign sysIO attributes directly in your source. You will need to use the attri-
bute definition and syntax for the synthesis vendor you are planning to use. Below are a list of all the sysIO attri-
butes syntax and examples for Precision RTL Synthesis and Synplify. This section only lists the sysIO buffer
attributes for these devices. You can refer to the Precision RTL Synthesis and Synplify user manuals for a complete
list of synthesis attributes. These manuals are available through ispLEVER Software Help.
VHDL Synplify/Precision RTL Synthesis
This section lists syntax and examples for all the sysIO attributes in VHDL when using Precision RTL Synthesis or
Synplicity synthesis tools.
