Problem Title: 
Viewsynthesis: BSCAN and Mode pin instantiation  
 
 
Problem Description: 
Urgency: Standard 
 
ViewSynthesis doesn't accept the instantiation of any symbol that has only 
inputs or only outputs, so the instantiations of the TDI, TMS, TCK and TDO 
symbols as well as MD0, MD1 and MD2 will be a problem. 
 
 
Solution 1: 
 
Since Viewsynthesis does not support the instantiation of these symbols, they 
must be added via the schematic entry. 
 
The steps are the following: 
 
1) Compile and Synthesize the VHDL code with the option: 
"create symbol" selected. 
2) Load this symbol in the schematic editor. 
3) Add the BSCAN symbol as well as the dedicated pads to the top level design. 
4) Save this new top level design. 
 
Note: The VHDL code can be re-synthesized as many time as necessary without 
having to modify the top level schematic, as long as the external I/O are not 
modified.
