Appendix A. HDL Attributes for Synplify
Using these HDL attributes, you can assign the sysIO attributes directly in your source. You will need to use the
attribute definition and syntax for the synthesis vendor you are planning to you to use. Below are a list of all the
sysIO attributes syntax and examples for Precision RTL Synthesis and Synplify. This section only lists the sysIO
buffer attributes for these devices. Refer to the Precision RTL Synthesis and Synplify user manuals for a complete
list of synthesis attributes. These manuals are available through the ispLEVER or Diamond 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
and Synplify synthesis tools.
