IBIS handling in pyaedt/src/ansys/core/circuit.py

[Ronaldo-SIPI]

Before submitting the issue

• I have searched among the existing issues
• I am using a Python virtual environment

Description of the bug

in
pyaedt/src/ansys/core/circuit.py
method -> create_ibis_schematic_from_pins

in line 2266 we have the issue
if ibis_tx_component_name:
cmp_tx = ibis.components[ibis_tx_component_name]
else:
cmp_tx = list(ibis.components.values())[0]
if ibis_rx_component_name:
cmp_rx = ibis.components[ibis_tx_component_name]

I try to test 2 different IBIS files (but are the same) and it fails

Steps To Reproduce

if you use the
https://examples.aedt.docs.pyansys.com/version/dev/examples/aedt_general/report/virtual_compliance.html

PCIe VC example the AMI part will not work if you specify the RX component
but in real world examples we will have 2 different ibis files and components and models

this error pops up

18 analyze=True,
19 design_name="AMI_RW",
20 )

TypeError: cannot unpack non-iterable bool object

---

ALSO
in the doc string the name tx_buffer_name and rx_buffer_name is NOT correct it must be renamed to tx_buffer_pin_name and rx_buffer_pin_name why the IBIS parser grab here the pins!!!

why???
