Unnecessary hack

[eschmidscs]

Hi

Why are you doing this with a netlist hack? You can enable this pin in the block design and wire it there.

AVED/hw/amd_v80_gen5x8_25.1/src/constraints/place.pre.tcl

Lines 23 to 30 in 839b4ad

	set PS9_IRQ_pin [get_pins -of [get_cells -hierarchical PS9_inst -filter { PARENT =~ "top_i/cips*"}] -filter { REF_PIN_NAME =~ "PMCPLIRQ[4]"}]
	if {[llength ${PS9_IRQ_pin}] == 1} {
	# Remove dont_touch
	set_property dont_touch 0 [get_nets -of [get_pins top_i/clock_reset/pcie_mgmt_pdi_reset/pcie_mgmt_pdi_reset_gpio/gpio2_io_i]]
	set_property dont_touch 0 [get_cells top_i/cips/inst/pspmc_0/inst]
	set_property dont_touch 0 [get_cells top_i/cips]
	disconnect_net -objects ${PS9_IRQ_pin}
	connect_net -hierarchical -net [get_nets -of [get_pins top_i/clock_reset/pcie_mgmt_pdi_reset/pcie_mgmt_pdi_reset_gpio/gpio2_io_i]] -objects ${PS9_IRQ_pin}

It actually caused quite some head ache here:

I did compare the complete block design, but not the hierarchy. But because I have changed the hierarchy, the script failed (with a minor warning).

Best regards,

For completeness: This enables the pin in question:

I find it hard to link the names, but the netlist ends up as wired by the script.
And the hot reset works for me with it.
