LMX2594EVM: Spurious not found in the simulation

OPA2141: OPA2141

Tvm TVMaintenance
Prodigy 70 points
Part Number: OPA2141
Other Parts Discussed in Thread: OPA141

On my attempt to get Net List had ERROR not found in the configured Libraries. using the simulation window attempted to add model libraries to design cache.

the found out could not save the work and this time got, "ORCAD Capture has stopped working" and gave two options Debug or close program. If it is at all possible please 

forward to me a reinstallation or the update key that I was given an option do but declined just before running into this issue. I thank you and hope to hear from you soon. Also do well come any other suggestion 

you may have. thanks

    Hi Stan,

    It is a little unclear what kind of problem you are having. It looks like you are using the Orcad circuit simulation program, with our OPA2141 PSpice model and encountering a Net List error? 

    Do note that TI now offers an online circuit simulator PSpice for TI which is a Cadence PSpice simulator. Cadence acquired Orcad in 1999, and modern op amp models such as that for the OPA2141 run in Cadence PSpice. If your Orcad software is older it may not be compatible with our modern OPA2141 model, or the current Cadence PSpice simulator. 

    I tested the OPA2141 (OPA141) in PSpice for TI and did a quick dc analysis. The model and software ran without incident and worked as they should. Shown below you can see the screenshot I captured from the simulation.

    If you would like to try PSpice for TI you can download it for free at the following TI webpage:
