Multidimensional array of registers

[Kjeld]

Hi,

I want to do something like:

<ipxact:registerFile>
<ipxact:name>RegisterArray</ipxact:name>
<ipxact:dim>8</ipxact:dim>
<ipxact:dim>4</ipxact:dim>
<ipxact:dim>2</ipxact:dim>
<ipxact:addressOffset>0x200</ipxact:addressOffset>
<ipxact:range>0x10</ipxact:range>
<ipxact:register>
<ipxact:name>RegArrayEntry</ipxact:name>
<ipxact:addressOffset>0x0</ipxact:addressOffset>
<ipxact:size>32</ipxact:size>
<ipxact:field>
<ipxact:name>MandatoryField</ipxact:name>
<ipxact:bitOffset>0</ipxact:bitOffset>
<ipxact:bitWidth>32</ipxact:bitWidth>
</ipxact:field>
</ipxact:register>
</ipxact:registerFile>

but so far I had to stick with:

<ipxact:registerFile>
<ipxact:name>RegisterArray</ipxact:name>
<ipxact:dim>64</ipxact:dim>
<ipxact:addressOffset>0x200</ipxact:addressOffset>
<ipxact:range>0x10</ipxact:range>
<ipxact:register>
<ipxact:name>RegArrayEntry</ipxact:name>
<ipxact:addressOffset>0x0</ipxact:addressOffset>
<ipxact:size>32</ipxact:size>
<ipxact:field>
<ipxact:name>MandatoryField</ipxact:name>
<ipxact:bitOffset>0</ipxact:bitOffset>
<ipxact:bitWidth>32</ipxact:bitWidth>
</ipxact:field>
</ipxact:register>
</ipxact:registerFile>

Do I understand it correctly that it is not possible to specify arrays of registers with multiple dimensions?

Hi,

You can describe multi-dimensional registers and multi-dimensional register files, i.e., a register element may have multiple dim element and a registerFile element may have multiple dim elements. So I am not sure why you "had to stick with" something.

Hi Erwin,

Thanks for your reply. I don't think it is clear in the standard that you can specify multiple dim elements. I would expect something like:

<ipxact:dims>
  <ipxact:dim>3</ipxact:dim>
  <ipxact:dim>4</ipxact:dim>
</ipxact:dims>

if the syntax should match the other objects.

Cheers,
Kjeld

Hi Kjeld,

Some elements have a so-called container element (like busInterfaces) and others do not have that (like dim). The standard is not always consistent in that respect. However, the standard always states how many occurrences (0, 1, or multiple) an element can have in both the text and the schema definition files.

Best regards,
Erwin
