Dynamic glitch check - on bus + variable level definition

sgserg

Hello,

1) Id like to create dynamic glitch check on multiple busses. Unfortunately when I select bus node for example "test<4:0>" the glitch check doesnt work. If I separate it by single wire: "test<4>", "test<3>", "test<2>"... The glitch check works. Id like to test 10 buses witch glitch check. How do I set it up the fastest? 

I wanted to get check.scs file and edit it for my nodes, because its much easier and faster to do in text editor than working with the GUI. But the file is simply ignored. I wanted to import the check with "Import device checks..." in the Assert and check window, but I get an error explorer-7523. It says it can import only device checks that were saved with the tool.

2) Can I use "design variable" to change the glitch middle level check? I found that its possible for the time window. But when I simply write the design variable name into the "Mid" column it instantly swaps back and says it takes only numerical inputs.

    If you define your checks in spectre syntax, simply reference it using Setup->Model Libraries. The import in the checks and asserts is not for importing a spectre-syntax file.

    I didn't check point 2, but you should contact customer support if that's the case (in current versions - you didn't mention the version used). I'm sure you could make it a design variable if you specified the check in an include/model file as specified earlier in my reply - it's probably the UI being too thorough in its checks.

    Andrew.
