Appendix A. HDL Attributes for Synplicity
Using these HDL attributes, designers can assign the sysIO attributes directly in their source. The attribute defini-
tion and syntax for the appropriate synthesis vendor must be used. Below are a list of all the sysIO attributes, syn-
tax and examples for Precision RTL Synthesis and Synplicity. This section only lists the sysIO buffer attributes for
these devices. These attributes are available through the ispLEVER software Help system.
VHDL Synplicity/Precision RTL Synthesis
This section lists syntax and examples for all the sysIO Attributes in VHDL when using the Precision RTL Synthesis
or Synplicity synthesis tools.
