Function Param</A>

<P>
|
|
This function allows the user to give parameters when creating a cell.
|
|
<BR>
|
|
When one wants to give values to two parameters, one can type on the shell :
|
|
<PRE>
|
|
python test.py -n 4 -w 8
|
|
</PRE>
|
|
The file <code>test.py</code> has then to contain :
|
|
<PRE>
|
|
nbit, nword = Param ( "n", "w" )
|
|
</PRE>
|
|
The letters typed on the shell must be the ones given as parameters of function <code>Param</code>.

How to instanciate your generator in another generator</A>
|
|
</H3>
|
|
|
|
<P>
|
|
One can create a generator and instantiate it in another generator.
|
|
<BR>
|
|
To do that, the model name of the generator must have the form : "file_name.class_name".
|
|
<BR>
|
|
Note that if the two generators are not in the same directory, the directory of the generator to be instantiated has to be added in the CRL_CATA_LIB environment variable.
|
|
<BR>
|
|
<P>
|
|
For example, in order to instanciate the addaccu created above in a cell :
|
|
<PRE>
|
|
n = 4
|
|
Generate ( "addaccu.addaccu", "my_addaccu_%dbits" % n
|
|
, param = { 'nbit' : n } )
|
|
|
|
Inst ( "my_addaccu_%dbits" % n
|
|
, map = { 'a' : self.netA
|
|
, 'b' : self.netB
|
|
, 'c' : self.netC
|
|
, 'v' : self.netV
|
|
, 'cmd' : self.netCmd
|
|
, 'cout' : self.netCout
|
|
, 's' : self.netS
|
|
, 'vdd' : self.vdd
