One memory loads and//    reorders data, while the other memory dumps the data to the output.//    Once loading and dumping of data are complete, the memories reverse roles.//    The dumping memory continuously cycles though the entire memory starting at address 0.//  //  Interface://  //    Synchronization://      clock_c  : Clock input.//  //    Inputs://      swap_i   : Swap signal to interleave memories.  Pulse occurs one frame before the switch//                 and may coincide with the last input data.//      write_i  : Write enable for input data.//      addr_i   : Address for input data.//      data_i   : Input data.//  //    Outputs://      sync_primary_o    : Output sync plus occurs one frame before data new dump.//      sync_secondary_o  : Secondary sync plus occurs one frame before data at address 0 is dumped.//      data_o            : Output data.//  //  Built In Parameters://  //    Address Width  = 12//    Data Width     = 16//  //  //  //  //  Generated by Confluence 0.6.3  --  Launchbird Design Systems, Inc.  --  www.launchbird.com//  //  Build Date : Fri Aug 22 09:33:11 CDT 2003//  //  Interface//  //    Build Name    : cf_interleaver_12_16//    Clock Domains : clock_c  //    Vector Input  : swap_i(1)//    Vector Input  : write_i(1)//    Vector Input  : addr_i(12)//    Vector Input  : data_i(16)//    Vector Output : sync_primary_o(1)//    Vector Output : sync_secondary_o(1)//    Vector Output : data_o(16)//  //  //  #include <stdio.h>#include <stdlib.h>#include <time.h>#include "cf_interleaver_12_16.h"static unsigned char n84[1];static unsigned char *sync_primary_o;static unsigned char n79[2];static unsigned char n58[2];static unsigned char n28[1];static unsigned char n27[1];static unsigned char n26[1];static unsigned char n25[1];static unsigned char n22[1];static unsigned char n21[1];static unsigned char n20[1];static unsigned char n19[1];static unsigned char n18[1];static unsigned char n17[1];static unsigned char n16[1];static unsigned char n7[2];static unsigned char *data_i;static unsigned char *addr_i;static unsigned char *write_i;static unsigned char *swap_i;static unsigned char n2[1];static unsigned char n1[1];static unsigned char *data_o;static unsigned char n59[1];static unsigned char n57[1];static unsigned char n57r[1];static unsigned char n57e[1];static unsigned char n57d[1];static unsigned char n32[1];static unsigned char n10[2];static unsigned char *sync_secondary_o;static unsigned char n45[1];static unsigned char n44[1];static unsigned char n35[1];static unsigned char n34[1];static unsigned char n33[1];static unsigned char n15[2];static unsigned char n15r[1];static unsigned char n15e[1];static unsigned char n15d[2];static unsigned char n48[1];static unsigned char n36[1];static unsigned char n49[1];static unsigned char n37[1];static unsigned char n66[1];static unsigned char n50[1];static unsigned char n38[1];static unsigned char n78[1];static unsigned char n78r[1];static unsigned char n78e[1];static unsigned char n78d[1];static unsigned char n71[2];static unsigned char n71e[1];static unsigned char n71w[1];static unsigned char n71aw[2];static unsigned char n71ar[2];static unsigned char n71dw[2];static unsigned char n71m[8192];static unsigned char n60[1];static unsigned char n43[1];static unsigned char n43r[1];static unsigned char n43e[1];static unsigned char n43d[1];static unsigned char n65[2];static unsigned char n65e[1];static unsigned char n65w[1];static unsigned char n65aw[2];static unsigned char n65ar[2];static unsigned char n65dw[2];static unsigned char n65m[8192];void cf_interleaver_12_16_ports(unsigned char* port_swap_i, unsigned char* port_write_i, unsigned char* port_addr_i, unsigned char* port_data_i, unsigned char* port_sync_primary_o, unsigned char* port_sync_secondary_o, unsigned char* port_data_o) {  swap_i = port_swap_i;  write_i = port_write_i;  addr_i = port_addr_i;  data_i = port_data_i;  sync_primary_o = port_sync_primary_o;  sync_secondary_o = port_sync_secondary_o;  data_o = port_data_o;}void cf_interleaver_12_16_calc() {  n84[0] = 1;  sync_primary_o[0] = n57[0];  if (n78[0]) {    n79[0] = n71[0];    n79[1] = n71[1];  }  else {    n79[0] = n65[0];    n79[1] = n65[1];  }  n58[0] = 0;  n58[1] = 0;  n28[0] = 2;  n27[0] = 0;  n26[0] = 0;  n25[0] = 0;  n22[0] = 1;  n21[0] = 2;  n20[0] = 0;  n19[0] = 0;  n18[0] = 1;  n17[0] = 1;  n16[0] = 0;  n7[0] = 1;  n7[1] = 0;  n2[0] = 0;  n1[0] = 1;  data_o[0] = n79[0];  data_o[1] = n79[1];  n59[0] = n15[1] == n58[1] && n15[0] == n58[0] ?
