Error of vsource type=bit. "Waveform type must be specified ..."

xxgenerall

Hi Mr. Beckett,

Following your advice, I tried the bit vsource to generate a bit flow. However, an error came up.

Here is my simulation circuit.

    I've read some post about the "CDS_Netlisting_Mode" problem. And I've checked the environment variable, as below.

    Mr. Beckett, can you help me, please?

    Thank you in advance.

    The version of spectre you are using is way too old. You're using a hotfix of a version of spectre that was released 10 years ago.

    You need to be using spectre from the MMSIM stream. In late 2004, we separated the simulators from the IC release to allow more rapid development of simulator features, and since then we have had MMSIM60, MMSIM61, MMSIM62, MMSIM70, MMSIM71, MMSIM72, MMSIM101, MMSIM111, MMSIM121 and MMSIM131. In other words, 10 major releases of the simulator.

    I can't remember exactly when the bit source was introduced. From some quick tests, it was sometime in MMSIM61 - so anything more recent than that will do, but I'd recommend using MMSIM121 or MMSIM131 as these are supported releases.

    Regards,

    Andrew.
