pass arrayed variable from ocean to design

DavidLou

hello experts,

I used arrayed variable in schematic to pass parameters from ocean script. e.g., param[0] for this device, param[1] to that device. 

in Ocean I declare them by 

               desVar( "param" "[111  1100]")

when such ocean script running, I got following error although the sim still continues. wonder if how I should fix it. 

*Error*   in the Design Variables.  AEL's message:  lexical error:
          lexical error at or near "["
*WARNING* asiiEvalDesignValList: problem with variable param

thanks,

David

  • Hi David,

    There have been a number of reports of this, including CCRs 1298763 and 1544251. The design variables are expected to be expressions using the Analog Expression Language (AEL), and that doesn't have support for vectors (that's what the CCRs I mentioned are about). So what happens here is that it gives an error and then passes it through to spectre directly and spectre can still handle the vector expression.

    So for now you will just have to tolerate the error. Might be worth contacting customer support to raise a duplicate request to increase the likelihood of something being implemented sooner rather than later.

    Kind Regards,

    Andrew
