John,
Here is a script I wrote a while back that answers this question.
if (find (port endpoint)) {
foreach (source, find("pin","*/CK")){
highlight_path -from source -no_auto_cycle endpoint
}
foreach (source, find("port")){
highlight_path -from source -no_auto_cycle endpoint
}
} else {
echo "please define endpoint as an output port on this design"
}
Change the structure as applicable as the command he is after is
highlight_path -no_auto_cycle. For example, one can specify an input pin
and an output pin for the same cell and that cell will be highlighted.

John,
This ain't so neat but seems to do the job (it worked OK for some simple
cases that I tried).
cell_name = "U216" /* Enter cell name here */
pin_names = cell_name + "/*" /* denotes all pins of cell */
filter find(pin, pin_names)"@pin_direction == in" /* find input pins */
input_pins = dc_shell_status
filter find(pin, pin_names)"@pin_direction == out" /* find output pins */
output_pin = dc_shell_status
highlight_path -from input_pins output_pin /* highlight path from
i/p to o/p */
The idea here is to use the highlight_path command in DC and use it to
highlight the path from the input to the output of the desired cell. This
makes DC highlight the cell for you.
