command line arguments into RC tcl scripts

kasyab

Hi,

  Is it possible to pass command line arguments (similar to argv in normal tcl scripts) into RC tcl scripts?

What I understand is that, when  RC is invoked with a '-f' option it invokes the script in its own shell and then invokes the script specified. Supposing that for example, within this shell I wish to choose a list of libraries from three sets of libraries I have access to, through an option passed at runtime, how will I achieve this?

The intention is to create fairly generic synthesis scripts for an environment controlled by make targets.

Thanks in advance,

Kasyab

    Hi Kasyab

    You can pass the library list and other variables from Makefile into RC. Here are the steps:

    In you Makefile:

    lib_dir = xx/yy/zz

    slow_lib_list = ${shell ls -1 ${lib_dir}/std_slow.lib} \
                    ${shell ls -1 ${lib_dir}/macro_slow.lib}

    fast_lib_list = ${shell ls -1 ${lib_dir}/std_fast.lib} \
                    ${shell ls -1 ${lib_dir}/macro_fast.lib}

    typ_lib_list = ${shell ls -1 ${lib_dir}/std_typ.lib} \
                    ${shell ls -1 ${lib_dir}/macro_typ.lib}


    In RC synthesis script:

    set_attribute library $env(slow_lib_list)

    Hope this helps.

     Any reason you cannot do

     

    rc -f script.tcl -e 'set libFiles {slow_as_molasses.lib honking_memory.lib}'

     Any reason you cannot do

     

    rc -f script.tcl -ex 'set libFiles {slow_as_molasses.lib honking_memory.lib}'

     Thanks grashopper and kazad. I figured out a solution similar to the one proposed by kazad. That was the one more suitable to my needs. 

     

    grashopper: I was looking for ways to switch entire library sets and as far as I know, the way to do this was by switching the search path for those libraries at runtime. I may not have understood your solution completely, but what I understood from it was that you set all the variables through the '-ex' switch; this would have proved quite tedious in my case.
