Hi,

Simulation results sometimes don't appear as below.

Could you tell me how to stop this symptom?

Hi Kuramochi,

I have reached out to the engineer that is responsible the WEBENCH model of the LM5155. They should get back to you shortly.

Thanks,

Garrett

Hi Kuramochi,

The values in the Performance summary table don't appear if WEBENCH could not find the Voltage /Current data within the simulation window. Could you please share the WEBENCH design using the 'Share Design' option?

Thanks & Regards,

Praveen

Hi Kuramochi-san,

We hav simulated the WEBENCH shared design.The simulation time was exceeding more than 15 mins due to which the simulation was getting failed.

Please note that the performance summary doesn't show up in the below case.

1. WEBENCH simulation fails due to timeout

2. WEBENCH doesn't load the waveforms within a specified time.

3. WEBENCH could not find the current /voltage within the simulation window.

We have changed the simulation analysis parameter to reduce the simulation time and all the test benches are getting simulated within 15minutes. Also, the performance summary is being shown for all the simulations. The changes will reflect on ti.com by the end of December

Please find the WEBENCH report:
