When a list is returned from the
get_* commands, the list is un-formatted and returned to
stdout in a single line delimited by a space. This is shown in the following example:
get_cells A B clk_IBUF_inst rst_IBUF_inst din0_IBUF_inst din1_IBUF_inst dout0_OBUF_inst dout1_OBUF_inst dout2_OBUF_inst dout3_OBUF_inst clk_IBUF_BUFG_inst
This un-formatted return makes it difficult to see what has been returned in the Tcl Console and
the Vivado IDE. To have each item in the list returned on a separate
line, simply execute the command nested in a
join command, with the
newline character, '
\n', as follows:
join [get_cells] \n A B clk_IBUF_inst rst_IBUF_inst din0_IBUF_inst din1_IBUF_inst dout0_OBUF_inst dout1_OBUF_inst dout2_OBUF_inst dout3_OBUF_inst clk_IBUF_BUFG_inst
The list returned by the
get_* command is unaffected by the
Note: When converting a Vivado collection of objects into a string representation, not all the objects have to be included in the string representation. The number of objects to be included in the string representation is defined with the parameter
tcl.collectionResultDisplayLimit(default: 500). Refer to section Collection versus String Representation for more information.
