Appendix C. sysIO Attributes Using Preference File (ASCII File)
Designers can enter sysIO attributes directly in the preference (.lpf) file as sysIO buffer preferences. The LPF file is
a post-synthesis FPGA constraint file that stores logical preferences that have been created or modified in the
Design Planner or Text Editor. It also contains logical preferences originating in the HDL source that have been
modified.
. Below are a list of sysIO buffer preference syntax and examples.
IOBUF
This preference is used to assign the attribute IO_TYPE, PULLMODE, SLEWRATE,PCICLAMP and DRIVE.
Syntax
where:
<port_name> = These are not the actual top-level port names, but should be the signal name attached to the port.
PIOs in the physical design (.ncd) file are named using this convention. Any multiple listings or wildcarding should
be done using GROUPs
Keyword = IO_TYPE, OPENDRAIN, DRIVE, PULLMODE, PCICLAMP, SLEWRATE.
Example
LOCATE
When this preference is applied to a specified component, it places the component at a specified site and locks the
component to the site. If applied to a specified macro instance, it places the macro’s reference component at a
specified site, places all of the macro’s pre-placed components (that is, all components that were placed in the
macro’s library file) in sites relative to the reference component, and locks all of these placed components at their
sites. Below are some of the LOCATE syntax and examples. For further information, refer to the ispLEVER Help
documentation in the Help menu option of the software.
Syntax
Note: If the comp_name, macro_name, or site_name begins with anything other than an alpha character (for exam-
ple, “11C7”), you must enclose the name in quotes. Wildcard expressions are allowed in <comp_name>.
Examples
This command places the port Clk0 on the site A4:
This command places the component PFU1 on the site named R1C7:
IOBUF [ALLPORTS | PORT <port_name> | GROUP <group_name>] (keyword=<value>)+;
IOBUF PORT “port1” IO_TYPE=LVTTL33 OPENDRAIN=ON DRIVE=8 PULLMODE=UP
PCICLAMP =OFF SLEWRATE=FAST;
DEFINE PORT GROUP “bank1” “in*” “out_[0-31]”;
IOBUF GROUP “bank1” IO_TYPE=SSTL18_II;
LOCATE [COMP <comp_name> | MACRO <macro_name>] SITE <site_name>;
LOCATE VREF <vref_name> SITE <site_name>;
LOCATE COMP “Clk0” SITE “A4”;
LOCATE COMP “PFU1” SITE “R1C7”;
LOCATE VREF “ref1” SITE PR29C;
