Command Reference2. FPGA Express Shell Commandsset_cell_max_fanout _N_A_M_E set_cell_max_fanout Set the maximum fanout for the cells in the chip. SYNTAX string set_cell_max_fanout [-_r_e_g_i_s_t_e_r] [_M_A_X__F_A_N_O_U_T] [_r_e_g_i_s_t_e_r__l_i_s_t] integer _M_A_X__F_A_N_O_U_T list _r_e_g_i_s_t_e_r__l_i_s_t ARGUMENTS -_r_e_g_i_s_t_e_r Required to indicate registers will be the target cells in the current chip. _M_A_X__F_A_N_O_U_T The required maximum number for fanout of each register in the current chip. _r_e_g_i_s_t_e_r__l_i_s_t Required list of registers for which the duplication is to be performed. DESCRIPTION This command duplicates all registers given in the _r_e_g_i_s_t_e_r__l_i_s_t so they will not have fanout number greater than the number _M_A_X__F_A_N_O_U_T. The user needs to specify -_r_e_g_i_s_t_e_r option as only registers are duplicated. _r_e_g_i_s_t_e_r__l_i_s_t needs also be specified. The current chip must be defined by using the command current_chip before executing this command, otherwise an error will be reported. The set_cell_max_fanout command must be issued on an unoptimized chip -- prior to issuing the optimize_chip command.
