MachXO sysIO Usage Guide
Appendix C. sysIO Attributes Using Preference File (ASCII File)
You can also enter the sysIO Attributes directly in the preference (.prf) file as sysIO buffer preferences. The PRF file
is an ASCII file containing two separate sections: a schematic section for those preferences created by the Mapper
or Translator, and a user section for preferences entered by the user. You can write user preferences directly into
this file. The synthesis attributes appear between schematic start and schematic end of the file. You can enter the
sysIO buffer preferences after the schematic end line using the preference file syntax. Below are a list of sysIO buf-
fer preference syntax and examples.
IOBUF
This preference is used to assign the attribute IO_TYPE, OPENDRAIN, DRIVE, PULLMODE, PCICLAMP and
SLEWRATE.
Syntax
IOBUF [ALLPORTS | PORT <port_name> | GROUP <group_name>] (keyword=<value>)+;
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
IOBUF PORT “port1” IO_TYPE=LVTTL33 OPENDRAIN=ON DRIVE=8 PULLMODE=UP
PCICLAMP =OFF SLEWRATE=FAST;
DEFINE GROUP “bank1” “in*” “out_[0-31]”;
IOBUF GROUP “bank1” IO_TYPE=LVCMOS33;
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. This can also be applied to a specified PGROUP.
Syntax
LOCATE [COMP <comp_name> | MACRO <macro_name>] SITE <site_name>;
LOCATE PGROUP <pgroup_name> [SITE <site_name>; | REGION <region_name>;]
LOCATE PGROUP <pgroup_name> RANGE <site_1> [<site_2> | <count>] [<direction>] | RANGE <chip_side>
[<direction>];
LOCATE BUS < bus_name> ROW|COL <number>;
<bus_name> := string
<number> := integer
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>.
