Detailed Description

The bels ensemble encapsulates the bel class from Vivado's Tcl data structure.

Function Documentation

compatible_with()

tincr::bels::compatible_with			objs

Get the BELs that the given objects can be placed on. Valid objects include lib_cells and cells.

Parameters

objs	The list of objects.

Returns

A list of bel objects that one or more of the listed objects can be placed on.

get_info()

tincr::bels::get_info			bel ?info?

Get information about a BEL that can be found by parsing its name.

Parameters

bel	The bel object.
info	which information to get about the BEL. Valid values include site or name.

Returns

The specified value as a string.

get_name()

tincr::bels::get_name			bel

Get the name of a BEL.

Parameters

bel	The bel object.

Returns

The name of the BEL as a string.

get_site_types()

tincr::bels::get_site_types			bel

Get the site types of a BEL, including alternate site types. NOTE: This command accesses a cached array that must first be generated. The first time this command is run in a Vivado session, it will take significantly longer than subsequent calls to the command.

Parameters

bel	The bel object.

Returns

A list of site types of the parent site object that include this BEL.

get_type()

tincr::bels::get_type			bel

Get the type of a BEL.

Parameters

bel	The bel object.

Returns

The BEL's type as a string.

get_types()

tincr::bels::get_types			bel

Get the alternate types of a BEL. Some BELs can change their type without changing the type of the parent site. Vivado does not provide a listing of these alternate types, and the only way to discover them is by placing a cell using the name of the BEL's alternate type instance.

Parameters

bel	The bel object.

Returns

A list of the alternate bel objects.

is_lut()

tincr::bels::is_lut			args

A simple proc to tell if a given BEL is a LUT

Parameters

bel	The bel object.

Returns

True (1) if the BEL is a LUT, false (0) otherwise.

is_lut5()

tincr::bels::is_lut5			bel

A simple proc to tell if a given BEL is a LUT5

Parameters

bel	The bel object.

Returns

True (1) if the BEL is a LUT5, false (0) otherwise.

is_lut6()

tincr::bels::is_lut6			bel

A simple proc to tell if a given BEL is a LUT6

Parameters

bel	The bel object.

Returns

True (1) if the BEL is a LUT6, false (0) otherwise.

is_route_through()

tincr::bels::is_route_through			bel

Is this BEL a route-through?

Parameters

bel	The bel object.

Returns

True (1) if this BEL is being used as a route through, false (0) otherwise.

iterate()

tincr::bels::iterate			var obj body

Iterate over the set of BELs associated with the given object.

Parameters

var	The name of the variable that will represent the bel object in each iteration.
obj	The object that will be queried for its set of bel objects.
body	The script that will executed each iteration.

remove_route_through()

tincr::bels::remove_route_through			args

Remove the route-through (i.e. replace it with a BUF cell)

unique()

tincr::bels::unique			args

Get a list of BELs on the device that is unique based on BEL type. TODO Remove args processing.
