CCSTUDIO-THEIA: CCS Theia SysConfig Switch not working for MSPM0G3507

JIngXiang Yang — Mon, 20 Jul 2026 03:50:31 GMT

Part Number: CCSTUDIO-THEIA

In the SysConfig view of my CCS project, I clicked the "Switch" button to change the device package/part number. However, after clicking, the page shows "330 items/options" but none of the specific options are actually displayed — the list appears empty or not selectable.

C2000WARE-DIGITALPOWER-SDK: 无法下载

一直不能下载，可以帮我解决嘛，只是学生想自己学习的

RE: C2000WARE-DIGITALPOWER-SDK: 无法下载

Lydia — Mon, 20 Jul 2026 02:35:54 GMT

您好，

帮您看了一下，这个软件下载是需要出口许可的，也就是需要您申请之后经过审批部门审批才可以下载，

https://www.ti.com.cn/tool/zh-cn/download/C2000WARE-DIGITALPOWER-SDK

您可以注意几点，

1，最好使用公共网络，不要使用公共内外或校园网，

2，在德州仪器官网右上角人像图标，下拉栏有个人信息，需要补全信息，包括邮寄地址等，

3，尽量使用公司邮箱。

如果您按照以上步骤仍不能下载，可能是审批方面的问题，审批问题需要联系客户支持中心，您可以点击下列链接，会有客服帮助您，

PSPICE-FOR-TI: Offical Library installation for Pspice-for-TI

muzi Hu — Tue, 07 Jul 2026 08:43:08 GMT

Part Number: PSPICE-FOR-TI

The Pspice-for-TI installed on my work laptop is limited by the work network. As a result, the app will show the followin session log when starting and the offical library cannot be installed automatically:

INFO(ORCAP-2463): Library download is in progress.....
ERROR(ORCAP-2466): Reinstallation of libraries could not be started. Try reinstalling libraries later.

I did find a method, that is to download the library file by the website https://software-dl.ti.com/pspice/esd/models/library/library.zip
However, are there any detailed steps to install the whole library at once, instead of importing models one by one?

LM5126A-BOOST-CALC: 关于LM5155-Q1的Pspice For Ti仿真Flyback Controller报错

QI YU — Sat, 18 Jul 2026 10:09:55 GMT

Part Number: LM5126A-BOOST-CALC

您好：

抱歉没有找到LM5155相关的型号选择。

关于LM5155-Q1的Pspice For Ti仿真中，Flyback Controller；Datasheet: SNVSAY4B EVM: SNVU629

出现报错：ERROR(ORPSIM-16592): More than one imported model containing transistors or diodes is detected. To simulate this circuit, a minimum of 1 and a maximum of 4 traces are required. Add at least one trace and simulate again.

我无法修改 traces 数量，也不能放探针，导致这个图纸无法仿真，请问怎样修改traces数量，或者有更好的决绝办法？

Hi, Alice

Thanks for your help. I have searched and read the post, that you shared with me, before I posted my question. I think the problem is not solved yet.

I think the only way is to teach me how to manually "import the entire zip file as a library" (step by step, I wish) because the company network issue cannot be solved easily. The method was not shown in the end of that post, e2e.ti.com/.../pspice-for-ti-error-orcap-2466-reinstallation-of-libraries-could-not-be-started-try-reinstalling-libraries-later.

我们给您如下建议

1）TI官网填写的个人信息中，公司名称和您的公司域名需要一致，其他也要按图片中所提到的保持一致。

个人信息在您登陆TI官网之后，点击右上角人形图标可以看到。

模拟 | 嵌入式处理 | 半导体公司 | 德州仪器 TI.com.cn

2）使用公共网络申请，不要使用校园网或者公司内网

3）非军用的话，不要错选军用。
