Newbie level 3
no pspice template
hello, currently i''m working on my project. im studying on a circuit and trying to simulate it on orcad capture. im using AD844 cfoas and LM124A opamp in my circuit. i created the model libraries for both components and placed those two files in orcad's default library folder. i draw the circuit on capture and tried to simulate it, but it an error occured, telling that there was an error while creating the netlist. when i look at the session log, it had those warnings and an error message:
WARNING [NET0093] No PSpiceTemplate for C1, ignoring
WARNING [NET0093] No PSpiceTemplate for R5, ignoring
WARNING [NET0093] No PSpiceTemplate for R1, ignoring

ERROR [NET0075] Unconnected pin, no FLOAT property or FLOAT = e U16 pin '28'
WARNING [NET0093] No PSpiceTemplate for U20A, ignoring
i placed those capacitors and resistors from orcad's model library named "discrete" . and there is an unconnected pin on one of the AD844's (current feedback op amp - CFOA), as it should be so in my circuit diagram.
why does it give those [NET0093] warnings? how can i avoid it? and is it wrong to have an unconnected pin on that opamp?
one more thing, im trying to do a transient analysis. the circuit im working on is a random bit generator thus it has no ac or dc voltage generators. im trying to let the capacitors to have initial voltages, is it possible to perform a transient analysis that way? im sending the circuit file as an attachment. thanks!
