I am using synopsis design compiler and Nangate Library for synthesis. When I want to insert scan chain in circuit I got the following message
Warning: No scan equivalent exists for cell iwb_biu/wb_cyc_o_reg (DFFR_X1). (TEST-120)
There is SDFFR_X1 cell which seems to be scan equivalent of this cell. This is same for all flip-flops and finally it cannot insert scan chain.
My script is working fine with other libraries. Is there any method to introduce scan cells to design compiler?
