| I see from chatter here that some folks use place_pins, but it seems not to work for me, with the error message showing in the title. My io.tcl is:
|
| -----
|
|
|
| set leftPins {}
|
| foreach port [get_ports _l_*] {
|
| lappend leftPins [get_property $port name]
|
| }
|
|
|
| set_io_pin_constraint -region left:* -pin_names $leftPins
|
|
|
| set_io_pin_constraint -region right:* -pin_names {
|
| _r_h_in _r_g_in _r_f_in _r_e_rot25 _r_e_rot11 _r_e_rot06 _r_e_in
|
| _r_d_in _r_c_in _r_l_in _r_a_rot22 _r_a_rot13 _r_a_rot02 _r_a_in
|
| _r_KW0_in
|
| }
|
|
|
| set_io_pin_constraint -region top:* -pin_names {
|
| _t_aCarryIn0 _t_aCarryIn1 _t_aCpropIn
|
| _t_eCarryIn0 _t_eCarryIn1 _t_eCarryIn2 _t_eCpropIn
|
| }
|
|
|
| set_io_pin_constraint -region bottom:* -pin_names {
|
| _b_aCarryOut0 _b_aCarryOut1 _b_aCpropOut
|
| _b_eCarryOut0 _b_eCarryOut1 _b_eCarryOut2 _b_eCpropOut
|
| }
|
|
|
| place_pins -hor_layers metal4 -ver_layers metal5 -min_distance_in_tracks 4

|
| which works fine until I added the place_pins command.
|
|
|
| I also used M4 and M5 for layer names (ASAP7) since those are what the openroad -gui viewer shows.
|
|
|
| Is this command blocked by something else? Is the track-multiplier not supported?
|
| Thanks! |

| You might try the recent -annealing options. @eder-matheus any further comments? |
| |
| ### maliberty |
| Would you include a screen shot of what you are seeing? Note that -min_distance means pin can be that close together at a minimum, not that they will necessarily be that close together if there is extra space available. |
|
|
| ### eder-matheus |
| @TanjIsGray Do you have a reproducible you can share regarding the minimum distance not being respected? We have a bunch of unit tests with different minimum distance values, and all seem to work properly. |
|
|
| ### TanjIsGray |
| I can share the source, make and tcl. These are not large, a few hundred lines of verilog. |
