How to set the reset value and mask per each field separately in ip-xact 2006.


Recommended Posts

 

In 4.6.7.3 Example register definition from IP-XACT™ User Guide v1.2.pdf, The following register definition demonstrates with a snippet.

            VNL...

           <spirit:register>                                                       
          <spirit:name>ureg1</spirit:name>                                       
          <spirit:addressOffset>4</spirit:addressOffset>                         
          <spirit:size>32</spirit:size>                                          
          <spirit:reset>                                                         
            <spirit:value>0x12345678</spirit:value>                              
            <spirit:mask>0xffffffff</spirit:mask>                                
          </spirit:reset>                                                        
          <spirit:field>                                                         
            <spirit:name>destination</spirit:name>                               
            <spirit:bitOffset>0</spirit:bitOffset>                               
            <spirit:bitWidth>14</spirit:bitWidth>                                
          </spirit:field>                                                        
          <spirit:field>                                                         
            <spirit:name>frame_kind</spirit:name>                                
            <spirit:bitOffset>14</spirit:bitOffset>                              
            <spirit:bitWidth>2</spirit:bitWidth>                                 
          </spirit:field>
          <spirit:field>
            <spirit:name>rsvd</spirit:name>
            <spirit:bitOffset>16</spirit:bitOffset>
            <spirit:bitWidth>16</spirit:bitWidth>
          </spirit:field>
        </spirit:register>

        ...

 

There is implemented only one register reset for whole fields of a register

                     <spirit:reset>
                        <spirit:value>0x12345678</spirit:value>
                        <spirit:mask>0xffffffff</spirit:mask>
                    </spirit:reset>

 

Is there any way to set the reset to each individual fields not only one? Could you guide me how each fields can have reset value ?

Hi,

You cannot describe register field resets in 1685-2009. The register reset value has to be used to compute the register field reset values.

Best regards,
Erwin

Thank you Erwin.

What IP-XACT version I can describe register field reset?
