In Simulink ,the pn sequence generator(essential blk) in frame based mode s not being accepted by the hdl converter. But the output of the pn sequence generator is given to a serial to parallel converter. What cud b the alternative for this?

Please check to see if the inputs are constants. If so, change the sample time on the constant block to be 1 or some such value.
One other thing you can do for your initial question is to get values to the PN sequence genrator serially, and take the output to a tap delay line from which you can get a list of multiple values. To ensure you get non-repeated values, you can use a downsample block right after the tap delay. Putting a uni delay block after the downsample genrates more efficient HDL code.
For a set of 10 values, PN Sequence (serial) -> Tap Delay (10) -> Downsample (10) -> Unit Delay

Frame based models are not supported by HDL Coder. You will need to convert your design to a sample based format. Frames can exist outside the portion of design being converted to HDL code, if necessary.
